Get it, Nintendo! It's a great game. Well, the racing part is, anyway (the battle mode, not so much).
Here's a link to the Polygon article, I strongly suggest you all add to the discussion over there and point out exactly how WRONG they were. :D

Curious to see how much the game manages in its first full week now. 3 million by the end of June looks like a distinct possibility!
Also, this is only the UK (who generally don't like Nintendo consoles as much as the rest of the world) but apparently Wii U sales increased by 666% over the previous week there, and most of those were Mario Kart bundles (yes, the title of the article is about Watch Dogs, I didn't post the wrong link):
