Dont hope too much for Pikmin 4, one insider said that Pikmin 4 was rebooted, but its seems that we will get Pikmin 3 port this at least.
I thought that the games Shigeru Miyamoto once mentioned (Pikmin 4 and Project Giant Robot) turned out to be Hey! Pikmin for 3DS and Nintendo Labo Robot Kit. I believe he said that Pikmin 4 would be quite different than Pikmin 3, which Hey! Pikmin surely was. He also said that the Pikmin franchise would strongly profit from 4K Ultra HD, which currently isn't possible with Switch. So I wouldn't be that optimistic regarding a new Pikmin for Switch in the near future (although I really like the games!).
No, Pikmin 4 and Hey! Pikmin are different games, and they don't have anything with Labo, also Miyamotoo never said something similar. Miyamoto 2 times confirmed existing or Pikmin 4 and he even said that Pikmin 4 was almost finished, one leaker recently said that Pikmin 4 exist but that game was reboted. Pikmin 4 was in development for Wii U first, and Nintendo than start moving game to Switch and probably during that process they reboted games.
Hopefully the recently rumored games, Metroid Prime Trilogy HD, Spyro Trilogy, Assassin's Creed 3 remastered all get officially announced. Very much anticipating Fire Emblem, so that's good. Probably gameplay footage of Joker rather than a new Smash DLC character this time. Not expecting Pokemon Gen 8 reveal until closer to E3.
Why is everyone mentioning assassin's creed 3? That game makes no sense. It's not loved like assassin's creed 2, it's not recent like assassin's creed Odyssey and it was already on the wii U and Wii U has a better game in AC4. So it's extremely idiotic to release Ass Creed 3 on the switch. Who even wants that?
Because of this, with only difference that Switch version will be most likely be announced in Direct.
