Two years is a long time for a major studio to stay quiet. Though it worked on some of the tracks for Mario Kart 7, Retro Studios has not shipped a major project since Donkey Kong Country Returns at the end of 2010. Since then, the company has been quiet, very quiet, without a single announced project that would require the full resources of the company. With a new Nintendo console on the way, the time seems right for Retro to once again showcase its ability to carry major Nintendo brands, this time in HD. Of course, there's also a certain rookie 3D portable that's just finding its legs - and dominating the handheld market.
