PhoneArena community member Sniggly has let us know that he received a soak test invite from Motorola for his Verizon Moto X. The invite doesn't mention what exactly the soak test is for, but that seems pretty easy to figure out. There's really only one kind of soak test coming from Motorola right now and that is for the Android 4.4.2 update.
The soak test hasn't begun, so there's no real way to say when the update will be approved and pushed out. As of right now, we have to assume that the update will bring the same things to the Verizon Moto X that it has to the other models, which means the addition of Google Cloud Print support as well as battery life and Microsoft Exchange bug fixes.
thanks for the tip, Sniggly!
