Now that's a little spicier! But I think it could definitely happen. At the very least, I don't think they'll show off Prime 1 Remaster without at least mentioning Prime 4 in some way, maybe with a small teaser or something.
My dream is that we get a "here's an upcoming game, and another thing for a related game" theme to the Direct:
- Here's Metroid Prime 1 Remaster trailer, coming this fall! Followed by a quick Prime 4 teaser, coming later down the line
- Here's BOTW2 big trailer! It's been delayed until Spring, as we already said, but here, have WWHD/TPHD as a nice consolation game for this fall!
- Here's a last-minute brief showing for FE: Three Hopes, coming in just a few weeks! Oh and btw, here's a reveal trailer for a brand new proper FE game coming this fall/spring!
