Despite the absence of a 100% solid release date, UK entertainment retailer HMV has started advertising preorders for both the black and white Wii U system in its stores.

Spotted by an eagle-eyed consumer and reported by GoNintendo, the promotion appears to be live in many stores up and down the United Kingdom. A deposit of just £10 is required to secure your order, although when you'll be getting it is another matter entirely — HMV can only vaguely state 2012 as the launch window.

Have any of our UK readers taken HMV up on this offer? Let us know in the comments section!
