They'll probably start with a short trailer, revealing the title and characters, dungeons, and overworld. Then they go to the Treehouse where the hosts will say what they will be doing (playing from A to B, or for 30 minutes or something) until they switch to Pokemon.
Did you not see the treehouse event at E3 2014? I dont know if they did it last year too, but in 2014 the treehouse was playing all the games showed during the Digital Event, with the developers. It'll be just like that, but probably with trailers in-between.
Bet with bluedawgs: I say Switch will outsell PS4 in 2018, he says PS4 will outsell Switch. He's now permabanned, but the bet will remain in my sig.
