The weather's been weird here in England today (or at least where I live)... It's just been a little cold, a little windy, but just grey and gloomy and gah... I also think I'm coming down with a cold, it's just that time of year though. That being said, I personally love Autumn and Winter!
Anyway, I read on Wikipedia that the WiiU will be released on:
November 18th - North America
November 30th - Europe and Australia
December 8th - Japan
Not sure why Japan's getting the WiiU last, but oh well. That's what I've read and I know the information could be inaccurate (since you can't always trust Wikipedia), but I'm sure we'll find out soon enough once all the WiiU ads start popping up on TV...
Edit; Unless there have been adverts already. I wouldn't know since I don't particularly watch TV all that much.
