Gaijin Games, creators of the BIT.TRIP games, is developing BIT.TRIP Presents Runner 2: Future Legend of Rhythm Alien and it will be appearing on the Wii U as a downloadable title from the Nintendo eShop.  I have not played the other games in the series unfortunately but I am planning to download this title once it comes out.  You can see video of some gameplay for Runner 2 below.
