I would agree with this. We don't need something more than 1136 by 640 unless Apple is moving to a bigger screen. 1080p is overkill by miles on a 4" iPhone 5.
My prediction is that apple will again double the resolution to 2272x1280 (easy for developers), make a phone with whatever larger screen size they want (somewhere between 4.3-5" to satisfy the people that love to hate

People will still complain about the lack of micro sd, removable battery, widgets etc...
Oh wait... Those aren't cool anymore? Teehee.
