That list has been there since at least January. Sure there will be a mini version of the N64 at some point, but the list is apparently totally unrelated.
Yes, it's all the games available on VC. Complete non-story. That said, it wouldn't surprise me if that ends up being the list (or close to it) as they are already emulated and don't have any rights issues.
The N64 would need to be different hardware from the NES/SNES mini. A raspberry pi struggles to run most N64 games and that is more powerful than the Nintendo efforts so far.
If that's true then Nintendo could have someone create a decent emulator on the existing hardware and make another hit retro console again. Heres hoping it comes with 4 ports!
