I will if its the same or very close to fidelity graphics in performance modes and locked 60fps, push out LoDs, RT and the like in 30fps modes. I don't care about 120hz modes at all, 8K is currently still a nonsense waste of time on console* since it would certainly be locked to 30fps just due to HDMI 2.1 bandwidth (Assuming PS5 Pro actually has 48Gbps 2.1, and not the 32 [or is it 40? I think thats Xbox] in the base PS5) and if it does have 48Gbps you could only get a 8K 60fps by downsampling chroma to 4:2:0 and/or using DSC which would look ass I bet.
*I can run some PC games from 10-15 years ago at 8K60fps on my GTX 1080 and they look magical, but most don't have the detail to bother doing that and its not viable for modern games obviously.
I'm a bit behind here, I need to buy a disc drive right now if I want to put discs into the PS5 Pro?
