I think the AR experience will be far more dependent on rock solid tracking and pose estimation, ergonomics of the headset, fashionability of the headset, ability to work in many light conditions, and killer initial apps, than display resolution or FOV.
Focusing too much on the display itself completely ignores the other aspects that inhibit adoption. An AR display that had a resolution of 100x100, could only display a green HUD, but was completely invisible inside a normal pair of sunglasses or glasses, would completely trump a super high quality fibre scanning display that was incredibly nerdly and unwieldly looking.
AR is pointless if you can't take it outdoors, if it's in-the-home only, you may as well go with VR.
