How come devs aren't gimping the PS4 multiplats to meet parity with Xbone?

The next games to be better on PS4:
AC4
NFS (Marcus Beer confirmed this)
Watch Dogs
Destiny
The Division
etc
Basically any non sports or race game

Have u got any proof ? 

Let's not forget COD: Ghosts and BF4.  And realgamer what more proof do you need, screens are out. Xbone has weak GPU and slow memory.
