Capcom Japan is running a teaser site with "newwarrior" in the URL, and it's little more than a quick Flash animation that lets you know its related to Street Fighter and an invitation to return at 5PM on the 29th (Japan time) to see what's up.
But thanks to a persistent series of very legit-looking leaks, I'm just going to go ahead and assume that the teaser site is counting down to the announcement of something called Super Street Fighter IV, which is a new version of Capcom's fighting game that, if the available info is accurate, will add new characters and moves to the mix. Here's a shot of one of the new characters, Juri:
But enough about that. The game will also feature T.Hawk as a playable character. Additionally, these screenshots match up with a list of supposed features compiled by EventHubs last week, which specifically mentions both of these new characters, along with other existing characters like Dee Jay, Dudley, Ibuki, Makoto, Adon, Cody, and Guy. Another new character named Hakan is also listed in the EventHubs article. Assuming this release will find its way back into arcades, this would also be a good time for Capcom to put the console-only characters from SFIV into the arcade release, giving that version Dan, Fei Long, Cammy, Sakura, and so on. But there's no real platform information out there yet, so we'll have to hold tight to see what the release plans are.
Gameplay changes are said to include two Ultras per character, the return of bonus stages, and more. Of course, this is all totally unverified, but with the images coming out and sort of backing up the list, I guess I'm willing to put a little stock in it.
Combine all this with a picture of someone posing with Capcom's Yoshinori Ono that shows bits of Super Street Fighter IV in the background and also sports a GamePro Germany watermark, and my guess is that Capcom held an event to show SSFIV to international press under embargo during the Tokyo Game Show last week and that official details will be hitting all over the place once that Capcom teaser site launches. Again, that's just a guess.
Or hey, maybe all of this info is fake and the screenshots are doctored! Stranger things have happened, right?
