Without looking at the screen someone might think you're watching Supermarket Sweep, but don't worry about that - it's Mario Kart Wii and it's a two-minute trailer.
After showing Mario and Luigi floating through the air (unlockable invisible Karts confirmed!) holding the Wii controllers, the trailer brushes briefly over all the features in the game, including a nice look at the awesome online mode that'll set a new standard for Wii online play.
It's worth bearing the happy-happy-joy-joy soundtrack for two minutes. Then, in case you haven't heard, you can go play the game for yourself at Game stores across Britain.
