It's not shocking, but hey, you'll be dancing with the Wii U Controller or something.

Just Dance is coming to Wii U in the near future, according to Ubisoft's 2012 Earnings Presentation.
The company actually expects Just Dance sales to dip this year, but the hope is that series expansion to Wii U and different geographical areas, such as Ubisoft's work with Nintendo in bringing the series to Wii in Japan, will bring sales back up.
The last Nintendo release in North America was last year's Just Dance 3. Just Dance 3 is being brought to Japan in July with help from Nintendo as Just Dance Wii 2.
Wii U is due out later this year. Just Dance on Wii U has no confirmed release date, but it could be included with the seven Wii U titles that Ubisoft is expecting to release by the end of March 2013.
Are they going to use the tablet?
I am willing to bet that Nintendo is making a camera/body sensor similar to Kinnect for Wii U. That would be supremely awesome.
If the tablets camera is used in ADDITION to the sensor bar maybe Nintendo will make the camera range adjustable in some way like the depth slider on the 3DS and you wont need that much distancd as you would kineticI don't see how that could work. The sensor bar doesn't actually sense anything, it's just a set of infrared LEDs that the camera in the Wii Remote picks up.
