You must wait.

Since the Wii U's unveiling at E3 in June and the vague announcement of a 2012 release date, we've all been hanging on to find out exactly when Nintendo's next console will be available. We'll all have to keep hanging on though, as that information won't arrive until next year.

Just as the 3DS release date was only confirmed a few months before launch, Wii U's price and release date will be communicated close to its actual release date, according to Satoru Iwata.

Since the Wii U we showed you at the E3 show in June was still in the development phase without very specific proposals on the software titles, we are going to announce the release date and the price next year when we are able to explain the specific proposals.

As is traditional, Nintendo will not have an official presence at Tokyo Games Show in September, so don't expect too much Wii U information until next year. Sit tight.
