We're pretty sure it has to be Android 4.4.2
Folks with an AT&T flavored Moto X (I hear it tastes like pickles) and have signed up for the Motorola Feedback network are getting invites for a new soak test this afternoon. While it's called "an early preview of a new software release," odds are that this is the Android 4.4.2 update like we've seen on other carriers already.
Thanks for joining the Motorola Feedback Network. We are inviting owners of the Moto X on AT&T to participate in an early preview of a new software release, and provide feedback. If you are not currently using an AT&T Moto X, please excuse and ignore this email.
Click this link -- [redacted] -- to take the enrollment survey if you wish to take part. Note that you must be a member in good standing of the Motorola Owners' Forums to be included. The registration window could close without notice so please respond as quickly as possible.
This is a confidential test under the terms of the Motorola Feedback Network. Do not post any details or information about this on any public sites.
Thanks -- please understand that start times are always fluid. We ask for your patience if you register but don't hear from us right away.
If you're not part of the Motorola Feedback program, there is no need to fret. Lately these soak tests have been short and sweet, and the general release follow soon after the soak begins.
Thanks to all the anonymous peeps who sent this in!
