Don't forget that those consoles won't come out for another year. By that time a 2070 will be midrange. Not hard to believe that consoles will be around that power.
Agree, next year even 3060 will be as powerful as RTX2080 . The jump from 12 nm to 7 nm+ is big on performance for Nvidia. PS4 back at the time are equal to GTX 660, which is a mid tier GPU back in 2013.
