Nintendo have issued a statement on their press conference to Game Informer
“Last year was the first year for Switch at E3, so we took a bit of a departure from our usual approach to E3, which is to focus on more near-term stuff. Last year, because it was the first year for the hardware, we looked at things that were maybe a little further out. This year, you can see pretty clearly, we’re back to focusing on the near-term. We’ll have more to share with Metroid Prime 4 when we have something we think is going to wow people.”
