Interesting tidbit from the PR for Pokémon: Let's GO (spotted by Joe):
So the game teased last year at E3 =!= not Let's Go. Wasn't expecting this, tbh, but it makes sense when you think about it. Let's Go definitely looks like something that started at about the same time Pokémon GO was released.
Pokémon also announced that the next introduction to its popular core RPG series, which was teased last year at E3, will arrive in late 2019 on Nintendo Switch for the first time.
