I doubt they would be making decisions for e3 this early. That would be just asking for leaks
Yeah I think they would not be too far ahead of themselves. They probably are planning a direct within the Spring time before thinking about presenting whatever they need to present for E3. I mean, the Pokémon RPG for Switch was likely due to the backlash of the Ultra Sun/Moon release for 3DS from the Pokémon Direct so things can change when necessary.
