Sega has recently announced their second foray into the Olympics, Mario & Sonic at the Olympic Winter Games, has sold more than six million copies since being released in October as an exclusive to Nintendo's Wii and DS consoles.

Considering they've had a four-month head start before the Olympics opening ceremony earlier this month, that's quite a draw. With the Olympics now in full-swing, Sega is planning on increasing visibility and marketing on the title.
