It may be a studio habit, there were many developers who only sent one version out to critics last generation.
But given the problems they were having with parity they may have sent out PS4 copies to hide a small difference in performance.
I was also under the impression that the Witcher 3 had some sort of collaboration with the Xbox One so I find it weird that they did not send out any copies of the Xbox One version.
Must be annoying for some potential Xbox One customers who may worry about performance issues.
This is the Game of Thrones
