can't believe no one mentioned this (or if it was the game's name wasn't used because it isn't showing up in search): a new RPG featuring
characters from Capcom and Namco Bandai and SEGA.
Capcom is bringing Ken and Ryu from Street Fighter, Zero and X from Mega-Man, Jill and Chris from Resident Evil, and Dante from Devil May Cry along with Demitri Maximoff from Darkstalkers.
Sega has Sakura and Ichiro Ogami from Sakura Wars, Akira Yuki and Pai Chan from Virtual Fighter, Kurt Irving and Reila Marceris from Valkyria Chronicles, Toma and Cyril from Shining Force, and Ulala from Space Channel 5.
Namco has Sanger Somvold from Super Robot Wars, Jun Kazama and Ling Xiaoyu from Tekken, KOS-MOS and T-elos from Xenosaga, Yuri Lowell and Estelle from Tales of Vesperia, and Kite and Black Rose from .hack.
hopefully this makes it over here.
[edit]
even more on the game. it looks more to be a fighter than an RPG.
