PDAdb.net has the specs (XT1254). If it carries all the LTE bands listed there, and has a reasonably bright display, I'll probably buy. Great battery life, strong support of almost every wireless standard, good build quality and comfortably usable in LTE on every US national network except Sprint. And, by the time it wears out, maybe Sprint too will have decent rural coverage, open access for devices and an end to stupid device locking policies. I was hoping to get the new Moto X, but the display isn't very bright, the battery is a bit of a worry and you can't get a version that supports both Verizon and AT&T on LTE.
A note on the Nexus. The Nexus 5 supports every single currently available US frequency, CDMA, GSM, HSPA, LTE -- except LTE Band 13. It's practically as though Verizon bludgeoned Google into keeping it off their network. So I have to say at this point, unless you're Apple and you're therefore too big to be bullied by a mere Baby Bell, Verizon WILL say, "bloatware or no-where!"
