In his opening keynote address at this years Quakecon, John Carmack declared both the PS4 and XBOX One consoles are “essentially the same”. He acknowledged that while both devices have different hardware architecture, Carmack remarked “Its almost wierd how close they are”. He also added “In the near-term, its going to be a good thing for developers and gamers” referring to the current generation of consoles challenges with development due to using two different programming standards.
