Nintendo just announced a new Wii U game: Lego City Undercover. The game is from longtime Lego developer Traveler's Tales. A portable version is also in the works for the Nintendo 3DS.
The gameplay reminds me of TT's "branded" Lego games, like Lego Star Wars, except with an original story. Juding from the brief preview shown at E3 2012, the game will use the Wii U Gamepad to scan objects.
The 3DS version will feature totally different content from the Wii U version, with it's own missions and different content.
