For the most part, most of the previous leaked pics of the Moto X are either of the device or were taken with the device. The above photo is neither of these, yet it still includes the Moto X, at least indirectly... This is a pic of a few assembly workers busily piecing together (or inspecting) the new Moto X phones at the Motorola factory in Texas. From the look of the pic, it appears to be a quality control testing area, or perhaps it's the final "check and clean up" section of the assembly process. Either way, it would be great to be a fly on the wall in there right now.
Motorola themselves shared this pic on Twitter last night: https://twitter.com/Motorola/status/357949257019437056.
