They'd better do it with MUA2. MUA suffered as a result of PS2 porting last time.
M:UA was the exact same across all consoles and handhelds (minus GBA and the exclusives). RavenSoft didn't seem to have a problem with PS2, PS3, 360, and Xbox before, the chances that they'll do it again are about 50/50 right now. But it's already confirmed for Spidey: WoS.
