bone fans and MS are going to be consistently upset paying $60 for inferior versions of the same game. I doubt MS will be able to do anything to force parity since virtually every big-budget multi-plat game will be superior on PS4 they can't moneyhat every single developer to gimp the PS4 version which will have superior results in one or more:
Lighting, Textures, Particle Effects, Physics, DoF, Motion Blur, AA, AF, HBAO, Reflections, Animations, Shadows, Scale, Draw Distance, Loading Times, Uber-sampling, 3D, VR, Polygons, decals, hair rendering, subsurface scattering, etc etc etc etc etc.
