Wow, 45 minutes?
I have to think that means we'll see a lot of 3rd party announcements coming, as I don't see how Nintendo could fill that time (unless there's another wave of 3DS games coming, which I rather doubt).
A wave of 3rd party announcements would be huge for the Switch entering the holiday season, especially if they wind up selling well. I certainly hope that's what we'll be seeing!
Otherwise, in my dream scenario we'd get the barest of glimpses or insight into Metroid Prime 4 or the coming Pokemon game, but that seems extremely unlikely.
