Nintendo isn't going all that well when it comes to Wii U sales, and their 3DS is a little flat when compared to their original NDS. That being said, it is still churning along and trying to compete against smartphones. We've seen quite a few revisions of the NDS and 3DS over the past few years and right now in Japan their is a new 3DS that's not quite XL, but not quite original. It looks to be all winner though.
The New Nintendo 3DS — out now in Japan, next month in Australia and New Zealand, and next year elsewhere — has a faster processor than its predecessor. It has customizable faceplates. It does a neat trick that makes the 3D effect much better. It even has a second analog stick (of sorts).
