The problem I see with exclusives like this, is that then the Switch Pro is no longer really a Pro version but more like a new console. It also could lead to people buying a game exclusive for the pro who have the regular, I mean, when the WiiU came out, there were people confused by the name, bought WiiU games and then found out they did not work on their Wii. Personally, I think a new "switch 2" console that is fully backwards compatible would have made more sense.. It is also a pity they never used that patent for additional computation module, something like that at least was rumored in the NX-codename stage, it would have been neat to have a dock that could add additional computing power.
One other thing, I find it odd that they would not go for a home-console only switch, especially with the Pro that would make sense, and it would be a cheaper alternative to the Pro that is both home and handheld, since you eliminate the cost of the touchscreen etc. And I mean face it, with the introduction of the switch lite, the whole switch concept was more or less thrown out.
