The main weakness of the ps4 and the xbox one is they haven't really jumped as far with regard CPU performance. Both have 16x as much memory and gpu performance is getting on 10x as powerful with ps4 but both consoles have perhaps only achieved 2-3x CPU performance over 360 and PS3 perhaps less when you factor in cpu overheads like the operating system and kinect on xbone. In CPU terms the PC slaughters both consoles and perhaps steam boxes and other x86 hardware will offer big enhancements over ps4 and xbone.
So because of this the ps4 may not remain competitive for very cpu intensive games later in life. It may be the ps4 approxmately can match the PC visually but in the background AI, physics etc will be reduced.
