So, basically starting back from square one I've decided to really do a bit of research into what the game may be based on the visual elements from the website. Of course this is all rumors and speculation, but I think I've found some solid "facts" that seem to be pointing to the legitimacy that this game is somehow directly related to the Street Fighter series.
Take a look at the following page elements taken from the Capcom Street Fighter III Third Strike website (found here):

Look familiar?
Well it should if you have visited the teaser site lately. Take a look at this taken from the teaser site here.

Of course, this could be just a case of coincidence and Capcom using a similar theme on its teaser site that they used in Street Fighter III Third Strike. But after the aforementioned rumors from EGM that Capcom was on the verge of announcing Street Fighter 4, perhaps this visual clue is a lot more "telling" then a simple similarity. In my previous post I mentioned that the idea that Capcom was working on Street Fighter IV finally was too good to be true, but with Street Fighter's 20th anniversary and a movie on the horizon, and now this teaser site, perhaps all the pieces are finally coming together.
What do you think? Am I reading too much into a visual artifact on a website?
UPDATE - Seems I may be a bit over zealous with my anticipation... Capcom Co. of Japan no longer owns the rights to Street Fighter (they are owned now by Capcom of America), so the chances of this being Street Fighter IV are slim. Guess it's back to the drawing board again...
