Mario and Sonic are due for another Olympics game to accompany next year's London-hosted event. Today, with exactly one year before the events start, Sega announced a release date for the Wii title, and a window for the 3DS.

The Wii game will launch on November 15 in North America, and November 18 in Europe. The 3DS version won't come out until February of next year, clearing yet another game off the increasingly lonely 3DS 2011 release schedule. New screens show off the Wii's 100m sprint (aka "the event that Sonic should always win"), and the 3DS 110m hurdle. The game boasts these along with new "Dream" events set in familiar Mario and Sonic environments.
