Power struggle: the real differences between PS4 and Xbox One performance

[Weedlab]

"One source even suggested that enforcing parity across consoles could become a political issue between platform holders, developers and publishers. They said that it could damage perceptions of a cross platform title, not to mention Xbox One, if the PS4 version shipped with an obviously superior resolution and framerate; better to “castrate” the PS4 version and release near-identical games to avoid ruffling any feathers."

Sounds about right. That's part of why I don't expect much difference from multiplats. It should be interesting to see how the exclusives stack up.
