More Wii U release date evidence

With last week's rumour coming out of Japan that the Wii U will see its North American release on November 18 it seems IGN have stumbled on more evidence pointing in the same direction. An internal Gamestop mail suggests that they have early indications that this will be the official release date for the new console.

We are likely to hear the official date at E3 this June, and hopefully a European date will also be announced then (worldwide street date?).
