It's been a rumor for a little while now, but Nintendo, at their press conference at E3 on Tuesday officially announced the Nintendo 3DS. Basically, it's 3D in your pocket. Nintendo spent the majority of their time on the 3DS, at least in the beginning, talking about how well their 3D works compared to the competition, especially considering there's no glasses needed. We're fans of that plan, for sure. And, just as we had heard rumored before, there's an option to turn the 3D on or off.
