Rumor: Nintendo plans to launch a new Switch SKU in 2020 - UPDATE: Nintendo says no

If they were to do a "Switch Pro" with better specs, the way they could get around the issue of splintered userbase is to do this

Pro Switch Specs:

393 GFLOPS undocked (which is the current Switch's docked performance)
800 GFLOPS docked (new higher performance mode for TV)

So old Switch models can't run these games, right? Well not neccessarily.

You can run these games on the older Switch models, but only the 393 GFLOP profile version of the game would run. This isn't impossible, it would just necessitate a battery pak when you are playing portably.

But this is really not a big deal, one can buy a 4500 MaH battery bank for $15, Nintendo could even offer an official one.

This way, games would run across all models, but the Pro model would be getting the better docked home performance is all.

Homebrewers on Switch are able to to get the undocked Switch to run at docked speed ... the system is fine, it doesn't overheat or anything. They're doing stuff like getting The Witcher 3 running at 60 fps undocked. It's just you lose battery life and that could be fairly easily augmented because batteries are dirt cheap and widely available. 

That sounds like a terrible idea or something that would be reserved for very few exclusives like the new 3ds.
