With the preponderance of 4K technology, and our consoles not even equipped to use it at all. Remember when consoles were supposed to push the boundaries of technology in what they can do? The PS1 made CDs the standard, Xbox made online services the standard, PS2 and PS3 with DVDs and Bluray. They also made significant leaps in raw power.
This generation? They don't seem to be bringing anything new other than gimmicks like Kinect. PS3 and Xbox 360 should have been replaced by PS4 and Xbox One in 2009 because if they had ... then we'd be playing with PS5 and Xbox 4 today. PS5 and Xbox 4 would actually push technology to new boundaries as they'd be more powerful and they'd be able to play 4K video and maybe even run games in 4K.
So far, PS4 and Xbox One? They're mini upgrades that should have been made all the way back in 2009 or 2010.
