Which is why people need to quit betting on anything before LATE 2020 for a potential PS5.........the technology is practically hitting its limitations AND not even game developers are able to make innovative game design beyond that limitation on "PC hardware" that is already miles ahead of consoles.
LATE 2020 is a more optimistic view on a potential next generation of gaming consoles, the realistic view in my feels it probably will be longer than that.
Only thing I can probably see happening is if Sony went the "nintendo-route" and made a new PSP/VITA that is like the Nintendo Switch with "PS4 Pro/Xbox 1 X-caliber" power........which is kind of a step backwards with Sony's approach to console gaming at the moment.
