SEGA has today released many new screenshots of the Wii version of Mario & Sonic at the London 2012 Olympic Games. In the screens we see the return of some Olympic events, but we also get to see some new Dream Events featured in the game. Dream Space Walk and Dream Rafting are based in levels seen in the Super Mario series and Dream Fencing is held in Sonic Heroes‘ Ocean Palace stage. You can find the 80 new screenshots over at Sonic Wrecks.
SEGA has also released two US TV ads for the game, which we have for you below. One has a Mario ending and the other a Sonic ending.
