Mario and Sonic at the Olympic Games is a big deal on the Wii, especially with the Leipzig crowd. Super Smash Bros. may have stolen some of its thunder recently, but the very idea of Sonic and Mario in a game together still holds a lot of power to many fans. Plus, if you don't own a Wii, Olympics on the DS is your only shot at Nintendo and Sega mascot characters competing at stuff.
Are you planning on going for the portable gold? Do you think this game has the potential to be any good? Are you eschewing the handheld release for the Wii version, or are you dedicated enough to making Knuckles and Yoshi compete in a judo match to get both?
