A User on Sonic Stadium forums has taken pics of what might be the box art of the next Sonic game. The next Sonic game is called Sonic Generations and is to mix up the old pot-belly faded blue Sonic and the more fit, taller, and much bluer Sonic.

Also, another posting has the logo for the London 2012 Olympic Games that will feature Mario and Sonic. This might be another Olympic style game for the Nintendo Wii.

Definitely look out for Nintendo and Sega to capitalize on the Olympic games with their popular mascots. Seeing as how well they sold the last Mario & Sonic Olympic game for the Nintendo Wii.
