Motorola has officially announced on its Google+ page that it will sell the unlocked Moto X for $150 less than the current pricing on Cyber Monday. The $150 discount will apply to all unlocked versions of the Moto X, including the desirable Moto X Developer Edition. With the $150 discount factored in, the sale will see the 16GB Moto X on sale for $349.99, the 32GB version for $399, both including Moto Maker customization. The Developer Edition will also be on sale for $399 from its current $549 price tag, though Motorola cautions that quantities will be limited on each model during the sale.
Update: Sale starts at 8 AM Central Standard Time.
If you have a grandfathered unlimited data Verizon plan, I would get up early and camp out via your web browser… Developer Editions on Verizon are supported by CyanogenMod and plenty of other ROMs if you miss the days of Galaxy Nexus being current.
