From WiiFanboy:

“Hot on the heels of yesterday’s news (and today’s, for that matter) on everyone’s favorite upcoming racer, Mario kart Wii, comes fresh screens depicting a variety of the game’s selling points. We get to see Mii integration, as well as a taste for some of the tracks making their way into the game, new and old alike. Not only that, but we get some screens for navigating the online arena and setting up a race.”
