There's a lot left for Nintendo to announce regarding the Wii U. We don't know a release date, but the firm has repeatedly said it'll be out this year. A price is also anyone's guess at the moment, with some reports placing it at £280, but others are expecting a lower price point.
With the original Wii Nintendo priced and dated it in September 2006, having shown it off at E3 earlier in the year. Assuming the firm uses a similar schedule, expect to hear the finer details in about three months.
