Segatron Genesis... call me the wizard.
A press release issued by Sega reveals that the handheld version won't be exactly the same as its PS3/Xbox counterpart -- a concept that should be comfortable to people anticipating a game about two different versions of the same character.
According to the announcement, the 3DS game has new levels designed specifically for that version, along with an unlockable 3DS-exclusive 'special stage.' Generations also uses the 3DS's StreetPass communication feature to unlock "bonus material" when two players' 3DSes come within communication range.
Slated for a November 2011 release.
