You are grossly over estimating running games at a higher res and more power, most don't care. Sony could not have 1 exclusive this fall and be fine. You forgetting people didn't just jump from 360 to ps4 because of power right? It was 100 more, kinect, DRM backlash.....those were all bigger factors.
Quite frankly people are overestimating what Scorpio is going to do. I doubt RDR2 will look that much better in Scorpio. Not to mention price will always be king and Sony has big marketing deals. Sony isn't releasing GOW in the middle of RDR, Destiny, battlefront etc
