Nintendo's long-anticipated follow-up to Double Dash!!, Mario Kart Wii, has nearly arrived. It's set to debut April 10, 11, 24 and 27 in Japan, Europe, Australia and America respectively, and it will come to the Big N's latest console complete with an online component. A 12-player online battle mode is amongst a host of online features included in the package. IGN took some time to play around with the offline portion of the game's battle mode and they're happy to report that, yes, it looks and plays like all of the Kart battle offerings before it, which is good news.
