I caught that too. My guess is that Sony saw the popularity/hype and offered them a sony sponsored marketing contract to guarantee they don't put it on XB1/WiiU/NX.
I have a feeling that FF7R is gonna end up with similiar terms -- but a 1 year exclusivity on PS4 first. (In other words, it lands on PS4 for 1 year then launches on PC and no others).
