Next Phone for us on the 2 year upgrade cycle

Well, it's coming up on that time to think about our next phone. It seems that Samsung and Verizon is hell bent to keep us from flashing our phones. I've been looking around here and it seems that most of the developers have gone to Nexus and LG devices. From what I've seen so far I might go to the LG G4+ I recently heard rumor about.

What phones do you think is going to be popular among developers?
