I agree on the 4k, I get it will look better but it's not a selling point for me to buy a system.
But I have to disagree on the games this generation. Considering I've played my PS4 daily since last fall I'm blown away with the last few games I've played. I can't wait for Uncharted 4 as that's one of my favorite series but considering everything else I need to catch up on before I even get to that, I probably won't get to it until the winter or next year.
So far this Generation has given me Mortal Kombat X, Dark Souls 2 Scholar of the First Sin, BloodBorne, Dark Souls 3 (Which I consider the Souls Borne series to be one of gamings best, I have to back track and play demon souls and darks souls 1), Halo 4, EDF 4.1, the new Madden game engine, Arkham Knight (Which I freaking love)
I still have to play Halo 5, The Witcher, Fallout 4, MGSV, and the new Tomb Raider. I can tell our taste are different but I wouldn't say this generation is lack luster by any means.
