I am personally disappointed and hope that rumor is incorrect. I was looking at a Switch Pro in terms of developer complexity, and what the easiest way to get to a more modern 4K system would be. With last-gen, both PS4 Pro and Xbox One X added one additional tier: you had base PS4, then PS4 Pro. Pretty easy. With Switch, every game already has to target two tiers: docked and undocked.
With a Switch Pro, literally ANY type of update to the main SoC, in both CPU and GPU power, should easily be able to hit the current Switch's docked performance while in handheld mode, with maintaining (probably extending even) the battery life. So with that being true, it would mean that Switch Pro portable mode would be the same developer-target as current Switch docked mode. Or another way of putting it: if a game on Switch right now targets 1080p in docked mode, it would simply run in that same 1080p mode while portable on Switch Pro.
The Switch Pro would then add one more, actually new third tier for games to run in: docked, 4K output. I do believe this would be 4K DLSS of course, but other perks could come into play as well (higher resolution textures, etc.) while using it. NVIDIA's DLSS is amazing in games that support it, and that is precisely why it would work so well here: being part of the Switch Pro's main spec means of course that every game can utilize it to its full potential, and probably provide even better results than what we have seen on PC just due to console's more close-to-the-metal and fixed development platform.
