The thing is, even with a 2070 doing 4k60fps is a very tough ask. I believe lots of people are expecting to see 4k60 across the board and they're gonna be very disappointed.
60fps is never going to be standard on console. I remember it being claimed/hoped of every new generation since the days of the N64 that "next gen will be 60fps as standard" and it never happens. Most AAA devs will always choose to double their rendering budget by going with 30fps.
Bet with Liquidlaser: I say PS5 and Xbox Series will sell more than 56 million combined by the end of 2023. (And over 130 million lifetime)
