We've been waiting for Android 4.4.2 in the US for quite a while, on the Moto X. We've already seen it launch in Canada on the Moto X and worldwide on the Moto G. We've also seen it hit the Sprint and Verizon Moto X's albeit unofficially. It looks like Motorola is starting the soak test for the update to Android 4.4.2 on T-Mobile now, as some users are already receiving invites to participate, remember you need to opt into the Motorola Feedback Network to take part in this soak test. Here's what the email says:

So it appears that we are getting an update, for us T-Mobile Moto X users. We're not 100% sure that it's Android 4.4.2, but it's very likely as we've heard from various Motorola engineers that it's coming soon. Which should fix the bugs with Android OS and such. Which will be a great thing for most of us. Hopefully the soak test will go well and we can get the update to everyone very quickly.
