There's been claims of a Switch Pro/Successor literally since launch
Speculation/wishlisting aren't claims. People talked a lot about a more powerful Switch because of the PS4 Pro/Xbox One X/New 3DS and assumed something similar would come for Switch. I don't remember any actual claims until the rumors of Mariko.
