Whether this Direct contains nothing more exciting than Mario's short trousers options in Aces (which is to say "very exciting"), you won't want to miss a second of the action as these Direct announcements are becoming more and more famous for the quality of their previously unannounced reveals.
Of course, the reason everyone will be tuning in is the off chance that Nintendo finally pulls the curtain back on the rumored Switch port of Super Smash Bros. for Wii U. In all honesty, nobody expected it to do as well as it's doing right now. You'll compete in one-vs-one bouts via the Nintendo Switch.
From what we've seen, Aces is a return to form for the series. This includes the various features that gamers can expect from the game, such as the different power moves and techniques that players can use to try and beat their opponents. The "Zone Speed" on the other hand, can slow down time, allowing players to block tricky shots coming their way.
Mario Tennis Aces will have an online 1v1 tournament - a beta, effectively - before the game's release on June 22. Something that has truly been lacking is the online functionality. As for the 3DS, it's far more likely that Nintendo will reveal some kind of major game for that system ahead of the biggest show of the years.
Finally, there are some new playable characters. Let us know down below! Mario, Luigi, Daisy are in the All-Around group, Bowser Jr., and Waluigi make up the Defensive group, Peach and Toadette are in the Technical group, Yoshi and Toad are in the Speedy group, Boo and Rosalina are in the Tricky group, and Chain Chomp, Bowser, Wario and Donkey Kong in the Powerful group.
