The game doesn’t launch until late June, but Nintendo will be holding a Pre-Launch Online Tournament (essentially a beta test) earlier in the month. Before we get to that, why not check out a couple new Mario Tennis Aces trailers? The first trailer is an introduction to Mario Tennis Aces’ story, while the second, longer trailer provides a more detailed overview of the game (the video is in Japanese, but it’s easy enough to follow along). >
