I seriously doubt Apple would bump the size but not the resolution.
It would be completely un-Apple like, and their first step backward since introducing the iPhone.
HD display with 3.9" screen...bank on that happening.
The Retina Display has been surpassed in resolution and pixel density. Apple wont leave that unchallenged. Never happen.
