Nintendo has announced their 2012 line up for the 3DS, DS, and Wii for both the US and Europe.
Some key first party titles for the 3DS, such as Mario and Sonic, Kid Icarus: Uprising, and their Circle Pad Pro add on launch early next year, with Luigi's Mansion 2, Mario Tennis, and Professor Layton all carry a vague "2012" release time frame. On the third party side, Resident Evil: Revelations, Rhythm Thief, Tekken 3D Prime, Crush 3D, One Piece Unlimited Cruise Special, and VVVVVV all launch early next year, with Metal Gear Solid: Snake Eater 3D being on the few announced titles for later that year.
The DS side of things is quite a bit smaller, with Inazuma Eleven 2 hitting Europe early next year and Devil Survivor 2 hitting America early next year as well.
For the Wii, Rhythm Heaven Fever, PokePark 2, and Mario Party 9 are all hitting the US and Europe in February and March. However, Europe is also getting The Last Story in February and Pandora's Tower in Q2.
