There is quite a big debate on whether the WiiU is sold out in places where it released. It is quite important because Nintendo intends to sell 5.5m WiiUs by March 31st, but also they also said that they would most likely produce only that many and "that [their] production capacity, rather than consumer demand, that will place limits on our Wii U prospects". In others terms, WiiU must be permanentely sold out (or sold on a just-in-time basis) for Nintendo to achieve its objectives.
This is where YOUR contribution is essential (especially if you live in the UK). The VGchartz community is diverse so I think we could get a pretty good picture if everyone reports the situation in his/her particular location. By the way, in the 13th district of Paris, where I work, there are WiiU available. I went to a big electronic/books retailer on launch day (at 1 pm) and 3 or 4 people were qeueing in to ask for a WiiU. In a specialized videogame chain store, there was no one buying a WiiU (there was nobody at all actually although it's usually busy at this time). I'll report again on Friday. Btw online retailers amazon.fr and micromania.fr (the video game chain I was telling you about) both have all the bundles available. Only game.fr seem to have nothing but the French branch of GAME is bust anyway.
So, do you see WiiUs on shelves around you?
