Among the slew of awesome games coming to the 3DS, a Sonic game is among a list of multiple titles cited for the 3DS. Taken from Nintendo’s press site:
Well, we get to see 20 seconds of old footage with at least 20 seconds of new footage! Also new screen shots for the DS version of Sonic Colors as well as the Wii version!
