Marvel Vs. Capcom 3 will be playable at this year's E3. The confirmed characters so far are Wolverine, Spider-Man, The Hulk, Magneto and Storm, and many other characters are confirmed to come back. Capcom says they "will be blowing fans out of the water with the sheer number of characters this game includes (on the disc)".
Yes, you heard it, the game will be released on disc, and it's going to be high-resolution mindless fighting. Furthermore, the gameplay will be 2D, with 3D graphics just like Street Fighter 4, and the game will contain many unlockables. It's rumored to be released in late 2010 or early 2011 for the Xbox 360 and Playstation 3, with no plans for other consoles so far.
