BoS and NCR have got some so it's not a guarantee.

Vertibirds are not exclusive to the Enclave. As mentioned, factions like the NCR and Brotherhood have access to them as well.

Even more so you can see in the trailer that it was a Brotherhood Initiate in the Vertibird.

It would be really lame if they were, IMO. Wouldn't make any sense to me.

How did Obsidian screw up factions?

By making them uninteresting.

You're either with a group who perpetrate some of the most cruel things you can do to another human being or you side with the big government.

House is a lame third because he is literally the generic grey area archtype present in any media such a character is allowed.

Every faction in that game is a caricature.

No reason to think that the Vertibird is indication of the Enclave as Lyons' BOS also has access to them (after F3) and its pretty much 99% probability that they are the BOS in the video shown flying Vertibirds with the Airship (which has BOS markings) and there is the BOS Vertibird being shot down by the protagonist in the same video......also the fact that the player can gain access to a Vertibird probably also points to Lyons' BOS rather than the Enclave, since the Enclave aren't well known for being very co-operative with non Enclave people.

Caeser legions scouts in Boston......why, the point of those scouts is to scout out the Legion's next conquest or existing enemies not to make a 2,000 (very roughly) mile journey (probably mostly on foot) to scout out the East Coast then track 2,000 miles back to report their findings, if any of them survived the trip.

The NCR could at least in theory fly at least some of the way, assuming that they wanted to risk a strategic asset like a Vertibird, but again to what benefit?

If we see any NCR members on the East Coast it would more likely be part of a trading group rather than a military force.

- NCR - they are on the other end of USA so they won't be there. But I can see Beth putting in an ex-ranger who decided to travel the world. Would not be the first character from West Coast to visit the East Coast

- Legion - it is doubtful that they even exist anymore as literally every prediction in NV suggested their collapse after Ceasar's death

- Mr. House - he studied at the Institute (which will no doubt be the central point of FO4's plot) so he might be referred in the game via a photo or some ancient text

- Enclave - I will be surprised if there is not some remnant, a minor base or a visitor from Chicago (NV hints that they have an outpost there) present in the game

New Vegas hints that they have an outpost in Chicago so I doubt that they are truly dead.

Of course they have the right: they own the entire Fallout license.

Will they? I doubt that they would do it if they don't have to. Most likely they will just try to hire Obsidian to make another west-coast spin-off in future (several interviews year or two ago hinted that both sides are considering another West Coast spin-off) and they will decide what is canon.

Its kind of strange that people still don't get that Bethesda are the ones who decide what is Fallout canon now.

I would certainly love another West Coast spin off, hell I'd like a few in the next long wait for Fallout 5.

That wasn't what I meant, I know that they get to decide canon, but what I was driving at specifically was an "unofficial" right, I know they own the license and they can decide what is what, but since Obsidian made the story and what not, wouldn't they have that 'right' to decide what is canon in that game? I would assume both would work together to decide what is canon and what isn't but I just assumed Obsidian would have a major say due to them developing and planning the game.

I sometimes think that questions such as these come from our fine European brothers and sisters, and I mean that with the utmost respect. As much Americans are often unaware of European geography sometimes I think those in Europe don't quite get how large the States is. It's roughly 3000 miles from East to West Coast. Given the post apocalyptic landscape I don't think it possible for either group to reach Boston in ten years with any appreciable numbers or infrastructure.

The main reason for them not being present isnt distance but rather why wud they be there, out of the two mentioned sure NCR cud theoreticly launch an expedition to reach Boston, lorewise they should be able to at great expences in both resources and manpower but there is no good reason for them to do it.

I thought they were very interesting, personally - certainly more interesting than you're trying to make them out as being.

I'd love to see an undercover agent from the Legion. Given how far the lore says Legion scouts go it wouldn't be unheard of to imagine that one saw the MWBoS, gave them a wide berth, and followed the old highways up north.

I mean, when it comes to mapping, I could see Caesar telling a Ulysses-type character to scout East until he found the Atlantic.

The MwBoS controls everything from Kansas to the Great Lakes.

You cant go north around them without going all the way up into Canada.

If a Legion scout was going to bypass the MwBoS, they would go south, through Texas/Oklahoma, and arrive somewhere in Georgia.

They could just wear normal clothes and no one would be the wiser.

Yes, but thats not what I was responding to now is it?

Guess it depends which highway he picks up, if they look like our modern system. If he picked up 44 he might scoot past them and follow that line all the way up through the mountains.

But, you're right, if he just kept his eyes pointed at the sunrise.

I read your post, you said "If a Legion scout was going to bypass the MwBoS..." - they wouldn't need to do any bypassing if they didn't look like a member of the legion, I'm merely pointing out that the idea of bypassing would be moot if a person just looked like an ordinary wastelander or trader.

Why, hello there, Vulpes.

The Legion didn't have the power to expand to take the NCR territory without a predicted choking-on-the-chicken-bone. What makes people think they could expand as far as the east coast?

Furthermore, the Legion is a monument to the ego of one Edward Sallow, who at best is on his deathbed by now due to the tumor in his head. It was not designed as a viable nation. Even if he is at best on his deathbed, the infighting probably would have already begun. I hope that the "after the Legion" isn't even worse than before in their territories once it all implodes.

If they took the 44 they would run into the MWBoS at St Louis.

There is also the problem of the Ohio River, you know, that River in The Pitt that's so irradiated one can get hundreds just by getting near it?

The only known crossing is The Pitt, and I doubt a Legion scout would survive that hellhole by himself.

Yeah, as any fighting force it would be absurd. The Eyes of Caesar, though...

As an aside, I forget: does the radiation in the air prevent long distance, say, ham radio communication?

So he ends up in Georgia with my southern cousins that make Point Lookout look tame.

I dont want either of those factions to appear in the east coast. Likewise I dont want an East Coast faction to somehow make it overto the west coast.

The enclave I doubt will be in FO4 (maybe fo6 ) due to them been basically dead and if they do recover it will take dacades if they can. NCR and legion are too far off and lack the ability and motivation, it's possible CWBoS could turn up (they have made the trip before and are desperate) but they are very weak and it would basically kill them off if they failed.
You could get NCR trader or escaped legion slave popping up but I doubt they would set canon for NV so what would be the point
