Seeing as there aren't any threads on this specifically, I decided to create this one. I am interested in people who can figure out what is on the perk wall. I would appreciate the minimum of argument, as I would like to fill this out as much as possible, and try to keep it in the realm of deliberation. These I believe are the perks that are in the game and what I think they'll do, some is based on what we've seen and others are just a hunch. This is mostly speculation, but I try to keep to what I feel strongly enough about (including any suggestions others may have). Many of these may also give special dialogue or environmental options.

Some of these have been taken from http://tamrielvault.com/group/fallout-character-building/forum/topics/perks-chart-news . You can buy one perk per level and they must be equal or lower to your SPECIAL score on that column. SPECIAL can also be increased instead of a Perk every level by one point according to http://www.ausgamers.com/features/read/3526651 . Additional changes are being made in response to this http://imgur.com/a/WJG4X and this https://www.reddit.com/r/fo4/comments/3g783x/fo4_perk_chart_better_image_quality_screen_grabs/ . Some additional changes are made from information I can not link, due to it being from the leaked gamescom video.

I have also listed what I have calculated to be the derived statistics (HP, AP, WT). I also now believe that as part of the 275 Perk Levels (the total being thrown around), 70 are specifically for your SPECIAL levels, which leaves about an average of 3 per Perk (some have more, like Gun Nut has 4). Reasoning is in brackets and VB = Vault Boy, and confirmed is meant to imply either actual or near perfect visual confirmation.

So, I figure I'd bump this after I added the Attack Dog and Intimidation Perks.

Very curious to see what the V.A.N.S. perk entails.

Me as well. I am not sure where I'd put the VANS perk, due to a lack of info of which column it'd be on. If anyone here was at quakecon and help with it's description and or location, that'd be cool.

very tough to guess this list out because of the levels of perks, which can add numerous and diverse effects to each singular perk

One question I'm curious about is we know most perks have more than one rank.

Only a few have just one rank so I've heard that counting all the ranks there are about 275 or so perks.

Are these ranked perks just going to be a fixed increased, or will there be variations each rank with maybe a bonus once you have all the ranks of that perk.

So say Demolitions 1 does +10% damage and +10 larger area of effect.

Will that be a straight progression so that Demolitions 4 does +40 damage and +40 larger area of effect, or will it include more?

Perhaps having all 4 ranks of Demolitions would do the above and include an extra like "And half damage from your own explosions."

Or Rank 1 of Power Armor training might allow you to wear Power Armor at -2 Agility and -10 Speed but Rank 2 would cancel those penalties, and rank 3 would give you an extra 10% Speed when in Power Armor.

See the following for what perks have been identified off the F4 Perk Chart.

http://tamrielvault.com/group/fallout-character-building/forum/topics/perks-chart-news

I wonder if in first person mode the criticals will work like they do in other games.

surely higher ranks in a perk will give you new abilities

i mean it'll probably be like increasing a %, but higher perk levels will also come with bonus new abilities alongside said % increases (level 1 increase %; level 2 increases % AND this ability; level 3 increase % AND another ability/power/whatever; etc)

most of skyrims were just % increases for layered perks and lots of people didn't like it, but i was ok with it since it was more grounded than FO

but i think Beth realizes FO perks need more crazy and pizazz and fun wackiness, and continuous new abilities with higher ranks is a good way to get that i think

I'm not sure what Demolitions will do, mostly. I am pretty confident that the usual Bottlecap Mine, Nuka-Grenade, or other explosives. I wouldn't be surprised if you are going to able to make more basic explosives. I also think that it'll cover disarming traps and potentially used to build more unique traps, like Shotgun Traps, Baby Carriage Traps, or Pressure Plates. There may be +dmg or +area elements, I don't know to what level though.

In addition I added a bit about Perk Chart, what you get at level up, and a few small adjustments to the OP.

Adjusted some things I think that Medicine or Strong Back may do.

https://www.youtube.com/watch?v=lLl0DVzRksk

I really hope you're right, here. My one concern with the new perk system is that a lot of perks won't feel like they have unique gameplay effects other than, say, '+10% damage and accuracy with guns".

Clearly, while in VATS you get the option to execute a special move in which a stampede of vans appear and run your enemies over. Pssh, clearly

Updating this list using reasons and added what I think the Perception 10 Perk will be.

With the posting of the higher-def perk chart, I've gone back and changed some of my original guess, more to come soon.

I doubt sandman is that simple this time around, especially since pretty much every perk is ranked if Petes high perk number is to go by, my guess is the sandman perk icon is used for a perk to increase stealth dmg.

Vault Assistant Negotiation System

Just updated this thread with the new unmentionable discoveries. I also added some other elements, like that I think that the SPECIAL increases are part of that 275 perk number.

Here's a http://www.gamesas.com/topic/1530622-completed-perk-chart-speculation/ that most believe to be a pretty accurate full perk list. Might find some explanation in there

I'm aware of that thread, in fact some of the ideas on that one come from this thread. Also, this was technically started before his was.

This is very true. I'm still really impressed that you spotted the ball being pitched from P2 to S2 when you did, when we were all using pixelated images! Which reminds me, I still need to add a mention of your findings in the OP of my thread, which I will do now. Thanks again for your many suggestions, and for noting the baseball reference in the first place

EDIT: done!

@Leprechaun, as noted on my thread, well done once again for your incredibly perceptive identification of the Slayer perk, albeit in a brand new next-gen guise. I should have listened to you on this one when you first mentioned it back in http://www.gamesas.com/topic/1529102-skills-perks-revised-edition/?p=24223998 post
