Here's what the product listing from Best Buy has to say about the game:
Take Yoshi on an epic adventure to remember in Yoshi Land for Nintendo Wii U. Check out Yoshi as you've never seen him before: in glorious high definition. Enjoy dual-screen control thanks to the Wii U Touchscreen GamePad, while you'll also be able to experience full integration with Nintendo's MiiVerse service.
Both listings carry a $59.99 price tag and show an expected release date of December 31, 2012, though it's worth noting that you'll commonly to see retailers use New Year's Eve release dates for games that don't have a confirmed launch.
