My predictions are pretty similar to yours:
-Super Mario Party as the main focus (similar to Mario tennis)
-New character reveal for Smash Ultimate. I don't think we'll see the mysterious new mode just yet.
-New Super Mario Bros Deluxe
-One or two big third-party ports (like Doom and Wolfenstein)
-Pokemon Let's Go gets shown some more
-Yoshi and Fire Emblem Three Houses will be shown briefly.
-Some 3DS games, like Mario & Luigi Bowser's Inside Story remastered.
