Jaw dropping graphics have already been done in games like Ryse, The Order, Forza a Horizon 2.
In FH2 you can literally see the different layers of paint.
The A.I. in MGSV does exactly this.
The A.I. In the Forza games is far beyond anything else in racing games.
The world in Witcher 3 is larger and more detailed than any game before.
The amount of enemies and chaos on screen in Sunset Overdirve is far beyond any game before, with almost no frame drops and physics, alpha effects not seen in this type of game before.
devs were literally complaining about being constrained by dvd sizes and not wanting to do multiple discs
you give them blurays on both systems and you dropping the same games that can be played on last gen... why?
Video takes up more space than anything, and there's been plenty of games released for this gen only.
All the games I listed are far more than just "slight" upgrades to last gen. And I didn't even list them all
I've been impressed plenty of times this gen, makes me wonder if you dudes who say their hasn't been anything impressive are just playing the wrong games
