After much speculation about "customizable" hardware, earth-shattering specifications, and groundbreaking construction materials, everything we've learned about the Moto X to date has been pretty... mundane.
No one seems to have nailed down a concrete list of specifications for the device, with rumors varying anywhere from Snapdragon S4 Pro - the chip powering the Nexus 4 - to NVIDIA's Tegra 4i. I'd like to point out that the latter basically isn't possible if the phone is being released this year, as when I spoke to NVIDIA 6 weeks ago, they said the first Tegra 4i devices will be coming in "early 2014." (That revising an earlier estimate of "Q4 2013 / Q1 2014.") However, there is some possibility, of course, that a Tegra 4i version will come at a later date.
