Perhaps... but Pandora is out of her box already. OEMs are under pressure to slap QHD screens in their flagships and most, with the notable exception of Sony, are happy to oblige. And while Sony has a perfectly reasonable and defensible stance on the issue, you can rest assured that when they release their next top of the line phone with a 1080 panel, one of the criticisms will be "Lacks QHD display".... I mean, if the Nexus 6 dropped with a 6" 1080 screen, no cries of "dat battery life" would shout down the howls from people saying that Google cheesed out and put a 'low rez' screen in there.
Now, for the 5" crowd... yes, there's absolutely no excuse for going to QHD... its silly. But once you get to 5.5" and above... well, you are going to be hard pressed to justify putting a less-detailed screen in a newer model. (The Nexus 6's pixel density is only an 11% improvement on the Nexus 5, even though it has nearly twice the amount of pixels)
