Here's some good news following up from our New Super Mario Bros. U release talk last week. Nintendo's Kit Ellis had said during an interview that New Super Mario Bros. U was going to be available for Wii U not too long after launch, which would seem to indicate that the game wouldn't be available day one. Now we have good news showing that you shouldn't worry anymore.
I talked to Kit Ellis, who told me that his comment was nothing more than a mistake. The intended release date is as Nintendo originally said. That means we still don't have a day and date, but the 'Holiday 2012' release still stands.
We also heard Iwata say that the game would be out day one with the Wii U, so it looks like we can keep believing that until told differently.
