Bold Prediction: Switch will ship >20m for 5 years

I think at this point, if a powerful Switch comes out like in the rumours, it will be a successor to the Switch and not a Switch "Pro" situation like you are suggesting. 2023 for a Pro revision will be crazy late as devs would have to support the base model.

By comparison, a PS4 Pro came out just 3 years after the base PS4 and One X came out 4 years after Xbox VCR. New 3ds came out 4 years after 3ds.
