I feel like we go through this rumor every month and wishful thinking gets people to read too much into things. Lack of gaming news? Probably just COVID disrupting Nintendo. New Pokemon game actually looks good? That's GF outsourcing development; at the very least, there's no way Pokemon Arceus is Switch Pro-exclusive--TPC prefers money to graphical fidelity. Nintendo apparently makes DLSS contract with Nvidia per Bloomberg? Okay, maybe there's something to that, but I feel like we've had this song and dance before.
Even if there is a Switch Pro, it'll probably be about as exciting as a 3DS-->N3DS upgrade. Games will have higher resolution and may perform better, but it'll still be a Switch and you still buy games for it when you care about portability over fidelity (or just want a Nintendo game). Idk, people talk about Switch Pro as if it'll be basically be a PS5/current year Xbox that let's Nintendo "catch up" when it's just a device that makes Smash look prettier.
