The Moto X XT912A seen there has the makings of a so-called Moto X+1. Powered by Android 4.4.3 KitKat, the handset looks to feature a 5.2-inch 1080p HD screen, a Snapdragon 800 processor, a 1.7GB RAM, and 24GB of internal storage.
The 12-megapixel rear camera is listed as having auto-focus, HDR, touch focus, and face detection while the front-facing 2-megapixel shooter would capture HD video.
It's worth pointing out that the XT912A model number was used by Motorola for the Moto X; the nearly identical XT912 is the model number for the Droid Razr. Perhaps Motorola is trying hide the new model in plain sight?
There is still no clear indication as to when we might expect the Moto X+1 to debut. The Moto X still has a few months to go before it hits the one-year mark, though Motorola promises we'll see the new device "late this summer."
