I just had a quick look around for stock in the UK which would be an indicator of a poor launch but can find no stock. It's all pre-orders only. I might be remembering wrongly but I'm sure there was still some wii u stock at launch time but maybe that was just the first day or 2 not 5 days after launch and of course that would depend on how much stock was actually available. Doesn't seem like the uk got a lot of stock.
I wonder how many people are waiting for the second wave of stock.
