NateTheHate is one of the most reliable leakers, so maybe this will be true, but Starfield uses a lot of CPU :X

So if I recall correctly he's also said Halo: MCC, MS Flight Simulator, and Forza are coming also and his track record is impeccable. 

I dont remember, but he said about Switch 2, Final Fantasy 7 Remake series for Switch 2 and Xbox Series, and many other things (I'm very tired now, so I'm lazy to search :X).

Nate's pretty reliable, so I can believe it.

With games costing as much as they do nowadays, it makes sense to bring them to the largest possible audience, so porting to Switch 2 is thew logical next step for MS's multiplat strategy.

Personally, I'd be more interested in the likes of Doom The Dark Ages, Hellblade 2, and Hifi Rush, hope they're coming too.

Hopefully the cpu of switch 2 is better than series s

No, It's not.

Its a bit better than the PS4 CPU, so they will need to optimize it very well or...

*waits for the inevitable Marvel's Spider-Man Remastered and Marvel's Spider-Man: Miles Morales to hit switch 2"

CPU stuff can be scaled in a number of ways; reducing density of crowds, simplifying character skeletons, updating stuff like cloth physics or distant animations fewer times per second, removing minor props and such to reduce draw calls, optimizing code to run more efficiently, etc.

On paper for instance, there's no way Witcher 3 or Kingdom Come Deliverance should run on three ARM A57 cores at a mere 1GHz, but the Switch versions made it happen.
