Texas-based firm Retro Studios has been confirmed as working on the development of Mario Kart 3D alongside an in-house Nintendo team.
As reported by Siliconera, the studio is building courses for the handheld iteration of the game, set for release over the 2011 Christmas period.
It was also reported during Nintendo’s press conference that the game will run at 60fps.
At the firm’s E3 press conference, Nintendo unveiled its ambitious new games console, Wii U.
At the centre of the new console is a built-in 6.2” touch-screen.
The controller can play content from the console without the TV switched on, or indeed with both screens being inventively used at the same time.
Data is wirelessly transmitted between TV and controller “without latency issues”, Nintendo said.
