Getting one in the UK is still nearly impossible. Its just a matter of luck. Comet had about 4 different packs in stock and sold out in a matter of hours. It was only the fact I was on at 6am in the morning I managed to get one. My girlfriend works at studio catalogues that also have them in stock and most people are ordering 2.
1 for them the other for ebay. Looking on ebay some on the prices are still fancy, the fairly priced ones seem too much of a good deal. It wouldn't surprise me if the one person bought all the wiis out at comet as it wasn't limited to 1 per person. They plan to sell the Wii at a profit and sell all the games as new on ebay.
EDIT: Comet sold out in about 20 minutes. Word must have got around fast. I must have found them being sold at just the right time. I had a choice of any of the packs as well, got the cheapest one with Wario. With the way Nintendo are messing europe around with not having enough wiis available, I can only assume America and Japan are getting them all.
