A new (and completely unverifiable rumor) is claiming that along with the Nexus 5, Google will be releasing an LTE model of the Nexus 4. The reasoning for this would be to keep the $299 price point with a 16GB model Nexus 4 LTE, and the models would bump up $50 from there. That would put the 32GB Nexus 4 LTE at $349, the base 16GB Nexus 5 at $399, and the 32GB Nexus 5 at $449.

Bummer. Still a great price for the Nexus 5, but... was hoping to save even more money.
EDIT: Actually, what the heck? I don't believe this rumor at all. Nexus 4 is done done, no? They're not going to produce more, are they? If they were producing more, even with LTE bands, couldn't they also continue producing Nexus 4 (non-LTE) versions? Did they really have to eliminate the Nexus 4 production to produce Nexus 4's with LTE radios? I'd think not, no? Why would Google/LG turn down the money that a continued fire-sale of the Nexus 4 would bring in? Doesn't add up..
I'm going to file this rumor as false. Just a gut feeling.
