[DISCLAIMER] This post takes the word "speculation" to a whole new dimension, please note that it is not intended to be taken seriously enough for anyone to start little secret cults of deranged conspiracy theorists. At the moment of writing it's late at night where I live and I haven't slept well at all for several weeks. (read: tired and somewhat braindamaged)
That said, I have loads of spare time and started pondering why TES V is so hush-hush. From a mathematical perspective I figured there should be clues all around that just need to be put together... Here's what I found so far!
The first legendary TES showed up at 1994 so lets make a timeline with major games and "less important" releases and call 1994 "year 0". Some of you will probably think I'm nuts when you see what I call "less important" but just hold that bashing thought until you have read all of what I have written, okay?
0 --- 1:Arena
1 ---
2 --- 2:Daggerfall
3 --- (Legends) Battlespire
4 --- (Adventures) Redguard
5 ---
6 ---
7 ---
8 --- 3:Morrowind, add:Tribunal
9 --- add:Bloodmoon
10 --
11 --
12 -- 4:Oblivion, add:Knights of the Nine
13 -- add: Shivering Isles
Looking at this you can see that the series appears to be picking up speed from "year 2" and onwards... But, with both TES number 3 and 4 (marked very clearly) there were some major investments in the games engine. Looking at the expansions gives us some idea of just how fast these guys can work with a completed engine and some basic items. (Yeah, they create a bunch of new artwork and quests at incredible speed once a game is released!) Now I'm gonna go theory on you, probably another excuse to bash me because I might just be incredibly wrong, just don't stop reading yet! They like their engine and may keep working on it, but even if they do there is the problem of compatibility and "bughunting". I just don't think it's possible to radically change the behaviour of something as complex as a game engine without the risk of it having a nasty impact on artwork already created. (read: extra work for the art team) With that in mind, these guys probably focus more on the engine at first and just aim to add a few extra features to it once the artwork team picks up speed. (yeah, I simplified that horribly but now everyone gets the picture)
Statements from the gamesas crew so far include hints at obsession over rich details and everything related to it. Years ago when talking about Oblivion they also told us about how important it is for them to react to the player's thoughts and how opinions about Morrowind shaped everything they did in one way or another. The first games were actually the largest ones in terms of landmass as far as I understand, then Morrowind offered a whole new experience and because of that radical change had to be cut in size. After Morrowind there was much to be learned and gamesas did their homework, lots of absolutely beautiful artwork but yet again a slightly smaller landmass! This time however the game was set where you could actually bump in to that horrible "please-turn-back-barrier" while just strolling around in the mountains, in a game that was all about freedom?! This was not very popular among many of us and the only logical step for the next game, I think most of us agree, would be either a new continent or the entire mega-sized world we've seen on the maps so far. Let's assume they at the very least increase the land to one and a half that of Oblivion this time, and with recent competitors showing off graphics that looks almost impossible to achieve in real-time... gamesas will haveto push themselves to the limit.
Oblivion was also not released until about two years after the first announcement, and the screenshots improved somewhat every now and then until the game was released. I was one of the players insanely hooked on Morrowind and started drooling all over the first screenshots. This rather long time of waiting made me expect pretty much what Oblivion turned out to be; an incredibly beautiful and still really big game. However, what it turned out to be was what I started expecting two years earlier! All that time felt like it was somehow wasted... Of course I can't speak for everyone but I bet a few others felt just like me, the excitement turning into impatience, turning into frustration...
Still awake? Good! Now, combine the three aspects we have above and you can figure something like this out:
There is really hard competition and gamesas would probably damn near rather kill themselves than release a game that doesn't get a gazillion "Game of the Year" awards... Fallout 3 was frankly just "Oblivion with guns" as some people put it. I mean no disrespect, the game was still incredible and I've lost countless hours in that horrifying wasteland and it's claustrophobic sewers and I have wandered the rotten earth and left the atmosphere in the expansion packs with much joy in my heart. That stated, the game was released just two years after Oblivion and was an amazing experience, again my hat comes off to the team creating the art because obviously they did a lot of the heavy lifting this time. Let's assume that the engine for TES V was on the drawing table already at this point, being secretely developed alongside that of Fallout 3, this would indicate that the engine had a cooperative start the first six months maybe? After the initial work it's possible they quite simply moved almost all programmers from Fallout 3 and had them work on the new version of the engine. By the time the artcrew was finished with Fallout 3 the new engine could have been very well two years in the making! Now that gamesas has hired a lot of people in recent years there should have been potential to sync artists and programmers over the last year and at this point they should be working like maniacs to create a world that will make every last one of us say "Wow... just... wow..." in total awe. (note: "wow", NOT "WoW"! Focus!) Optimistically, we can expect the first screenshot before next christmas and a game about a year later. As someone pointed out, they might replace "Brink" in the list of games they are working on so we may see the first proof of TES V close to the release of Brink!
All of the above does of course not take in to account the "behind the curtains" of the game "Brink", simply because I have no idea if more than a few in the TES crew have anything to do with that game. Like I said, gamesas has been hiring and it's not easy for us on the outside to know where these new employees go... *IF* Brink will be closely related to TES V, then I still think gamesas already has a bunch of people doing artwork already. Just look at the game previews, that engine is something else! (seems finished enough to start putting stuff into it that would fit in TES without fear of having to redo much of it as the engine gets fine-tuned)
Oh my! This was a hefty load of... text... But I'm still not sleepy enough, gah! Hope my thoughts can inspire some of you with a bit of hope, worked for myself atleast...
Almost morning over here now... Time to see if I can sleep, if not then I bet someone will LOVE to discuss recent technological advances in microchips and my slow progress in cheap capacitor research.
