From what I hear, there will be other carrier versions of this phone with a different name. The Droid Turbo is basically a souped up version of the Motorola X (2nd gen) complete with a 3900 mAh battery which will likely provide the longest battery life on any flagship phone and Morotola's rapid charging tech.
I have used and love the last two generations of Nexus devices but the Nexus 6 just doesn't interest me. I had warmed up to the idea of a phablet, despite the difficulties it might present when taking my phone running but the price really killed it for me.
