Anyway, you're specs are too low. At least for the Tflops. 16 GBs of GDDR6 is probably what we're going to see in the PS5, but 8 Tflops isn't going to be enough to for Native 4K. It's also not enough to warrant a $450 price tag in 2020. My guess is we're going to see something closer to 12 Tflops, coupled with a much better CPU compared to the Jaguar found in the PS4 and XBO.
Exactly, 16GB may not be surprising but the rest is a joke even for a $400 price at that point.
People fixate on "4K" like that is enough for new console, it's not, that's just a beefed up XboneX.
Graphics will be more than just resolution, and GPU will be for GPGPU along with better CPU.
I'm somewhat anti-VR myself, but next-gen VR will be big driver of capability as well, realistically.
But if somebody is happy with their PS4/Pro now, that's fine, you don't need to be hyped on PS5.
Plenty of people don't buy new consoles in first year or even 2, wait for the slim or pro version.
