Sonic Generations is yet to receive an official confirmation from SEGA, but Mario & Sonic London 2012 Olympic Games certainly seems plausible enough.
SEGA has only recently trademarked Sonic Generations and fans link it with the recent anniversary trailer that appeared for Sonic on Facebook as it showed two generations of Sonic. SEGA has offered the traditional 'no comment' to these alleged box art leaks.
Rumour: Sonic Generations and Mario & Sonic Olympic leaks?
