That's interesting and all, but I still don't see a reason to upgrade my PS5 to a Pro, and frankly it wouldn't even be that interesting for the price as a new player either.
Are there like any games that will really make use of the new hardware? Other than perhaps upgraded framerates and better 4K support. The average console player probably isn't going to care that much, not for the giant price increase over minimal gains.
I feel like all games on this generation will still be limited to the base PS5 anyway, can't imagine hardware matters much until the next generation consoles.
