At an ongoing first-party roundtable discussion at E3, Nintendo’s Shigeru Miyamoto revealed that the developer working on Mario Kart 3DS is one you all are likely familiar with — Retro Studios, makers of Donkey Kong Country Returns and the Metroid Prime series.
[Update: Other reports indicate Retro is collaborating on the title with another Nintendo house, co-developing or contributing to the tracks and other content.]
Miyamoto also says that Mario Kart 3DS, which will release later this year, will run at 60 frames per second. He mentioned that he originally wanted to call the game Super Mario Kite, too, due to the glider portions.
Here’s the Mario Kart 3DS trailer we posted earlier. From what I’m hearing on other sites’ hands-on impressions, the hand-gliding portions are actually fun. I’m more excited about the kart customization stuff.
