Jeez I screwed myself out of points last year once again by going into too much detail. Seriously, need to be brief this year to get the win.
1. No Switch successor will be released in 2023
2. A new 2D Mario game will be revealed
3. A new 2D Zelda will be revealed
4. A DLC expansion for Pokemon SV will come out
5. The rumored new Donkey Kong platformer will finally be revealed. Not going to predict if it'll be 2D or 3D though since I think it could go either way.
6. Kid Icarus Uprising HD remaster announced
7. Regular Gameboy and Gameboy Color get added to basic NSO, while Gameboy Advanced title will be part of the Expansion Pack.
8. The Metroid Prime 1 HD remaster is finally announced
9. An HD remaster of F-Zero GX will be announced
10. A new Wario Land from Good Feel will be announced
Prime 4 is turning into Duke Nukem Forever
Not exactly. The original developer was Bandai Namco who screwed things up so badly, the entire project had to be rebooted from scratch. Retro themselves have been working on the game since late 2018/early 2019, which is only 4 years now. The game will probably be out in 2024 which would give it a 5 year development cycle from Retro which is pretty normal from some of the more ambitious 3D games Nintendo releases.
The only reason I didn't predict a Prime 4 trailer this year is because part of my does wonder if the game might have been moved to the Switch successor. The Switch successor is probably coming out in the 2nd half of 2024, so if Prime 4 has been moved to it, we won't see any trailers until early 2024.
