We already know Mario + Rabbids Kingdom Battle and ARMS is gonna be there but what about new reveals?
This is my prediction list:
-Super Mario Odyssey for sure, since it's confirmed. I really hope they add multiplayer or online co-op (but that will be very unlikely). The Reveal of Luigi and Toad as playable characters?
-Since Mario Kart 8 Deluxe has been doing great lately, I'd say we get something extra for the game? I'm not saying a whole DLC pack but just a bit more content.
-Mario & Sonic At The Pyeongchang 2018 Winter Games
-Super Mario Maker Deluxe or a Super Mario Maker port of some kind.
-I'd say Mario Party 11 is way too early as for now.
-Kirby’s Blowout Blast
I'm guessing this might be the only Kirby title we get.
-Pokémon Ultra Sun & Moon will be there I guess. Maybe some more details.
-Teaser for a Nintendo Switch Pokémon Game?
-Release of the Animal Crossing Smartphone App after E3?
-I'd say it's way early to get a trailer for Animal Crossing Switch
-We know that Sonic Forces is gonna be there, we're most likely going to see alot more customizable options for avatars.
-Splatoon 2 is gonna have more weapons, etc.
-I do saw some people mentioning "Nintendo Party". It might be there assuming they want to keep the "Nintendo Land" feeling but for Nintendo Switch.
-A new Wario(Ware) game?
That's all what I got for now.
