The game will run at 1080p/60fps on the PS4, 720p/30fps on PS3 and native resolution on Vita in 30fps.
As for how the DualShock 4′s touchpad will be integrated into the gameplay, Pilestedt stated that, On the Vita we will use touch-interface for certain commands, with the PS4 the touch pad will as of now only use the click-down functionality. At Arrowhead were pretty stubborn about using tech just for the sake of using tech we believe that each feature that goes into the game needs to use the most sensible option for that control.
This doesnt mean that we think the touch-pad is bad or a gimmick in any way; it just isnt necessary for this title but we do have some ideas of how to use it for future projects.
