One of the new games announced during the Nintendo 3DS event in Japan was Mario Tennis. This series made its first appearance on the Nintendo 64. Now, several years later, and Mario Tennis will make an appearance once again. This time, you can be sure that he will be in full 3D.
On top of that, it will feature gyro control. How will that work on a handheld? Surely, we will not be swinging our 3DS around.
Look for Mario Tennis to hit the 3DS sometime in 2012.
