We've seen some reports suggesting a PlayStation 5 due this year! It's not going to happen, but realistically just when can we see the 6x to 8x leap in power that typically defines a new console generation? And when will Microsoft follow suit?
This video is from Digital foundry. I won't dump it on Dtube but direct you to its channel instead.
If you are interested in the PS5 (As I am), then its worth a look.
