Graphics are already more than good so it is just a gimmick. Is ray tracing gonna make a game better? No. Just give me good games.
I'm sorry but have you not seen the reception PS4 games get for being pretty or AAA games in general?...
All graphics are a gimmick by that lose definition you label it with, graphics will keep on improving whether you neanderthals like it or not.
That is why, they are already pretty. Ray tracing is not a selling point, good games will be :) and some of us had enough of the movie games. Time for variety like the PS3 days.
