Street Fighter 4 announcement in Japan later this week?

With all the retro fighting-game compilations Capcom has pumped out recently, we have to wonder whether they've completely ceded the (2D) fighting genre to the likes of Guilty Gear or those endless King of Fighters packs. (We could consider an anomaly like Capcom Fighting Evolution, but seriously, let's not.) For the fighting faithful, what we want more than anything — more than another vs. title or a killer (slow) strategy-RPG crossover — is a true successor to Street Fighter (whether you wanna go back to II or III for your favorite 2D inspiration). Well, folks clamoring for more Ryu-Ken craziness can wait a few days longer because Capcom is set to show off a new arcade fighting game at the Amusement Machine Show in Japan September 1-3 (this week!), though no official details of what the game is have been released. An unofficial list of games currently circulating online, however, states that SF4 will be making an appearance at Capcom's booth. Even if such a game will only be shown in video format, you can imagine the pandemonium that might ensue, if these rumors prove to be true, once the doors are open to the public on the 3rd (especially considering that admission is free). Rumors of a continuation of the Street Fighter series from this year's San Diego Comic-Con may finally be confirmed… or not. Here's hoping Capcom's got something good in store for us.
