As expected, Capcom has made the return of MvC2 official via Capcom Unity. The biggest news: a demo of the game will be available on PSN this week (most likely during the usual update on Thursday, April 30. Christian Svensson, the company's VP of strategic planning and business development, calls this the "definitive version" of the classic fighter, providing some details to back up his claim.
In addition to the already confirmed online play, it's been revealed that the game is based on the Sega Dreamcast release, features HD upscaling and widescreen options, and will support custom soundtracks on both platforms. Also, all 56 characters will be "unlocked" from the beginning. No word yet on a 360 demo, but we've dropped Capcom a line for comment. [PlayStation.Blog confirms the demo is exclusive to PSN.]
