I don't know why people keep saying November like it's certain. These snippets from Sega, Ubisoft or whoever aren't definitive. And Jason from 5th cell said, right here, that he doesn't even know, and probably only Nintendo knows.
And looking at the last few historical console launches isn't relevant because that information is trumped by basic business sense. Why would Nintendo launch the Wii U after BLOPS 2 comes out on November 13th? That is just plain dumb. The probably should get it out before AC3 on October 30th.
