SEGA has unveiled two new trailers for their upcoming sequel to the best-selling Mario & Sonic at the Olympic Games. It was just over a week ago that we were finally treated to the first gameplay footage of the title, and now they're back with more, not only for the Wii, but the DS as well.

First up, the Wii trailer shows us what seems like some natural pairings of characters and sports, as heavyweights Bowser, Eggman, and Donkey Kong decide to see how fast they can get a bobsled to move down the slope. Plus, Shadow the Hedgehog seems like a natural for skating events:



Next up, the DS game shows its stuff with several events. And considering the handheld's power, it looks like it holds up pretty well.



Of course, I'm still eager to see more of the Story Mode and how that will play out.
