Lets say the PS4 would be weaker than the Xbox One,
-Xbox One 1080p
-Exclusive and games stay all the same except that they run on higher or lower resolution.
-OS and features stay for both consoles the same
-PS4 would be the one for 350$ while Xbox One would be 400$
For me i would still play on the ps4 like i played on ps3 over the xbox 360
