Yeah, yeah. The new Nexus 5 is the first with Android 4.4. But if you're sitting on one of those other Nexus devices — as in 2012's Nexus 4 and Nexus 10, and the Nexus 7 (we presume both the 2012 and 2013 versions of it), know this: You'll be getting KitKat in the coming weeks as well.
In addition, the Google Play Edition Samsung Galaxy S4 and HTC One also will be updated.
Here's the exact word from Google:
We’ll also be rolling out the Android 4.4 update worldwide in the next few weeks to all Nexus 4, Nexus 7, and Nexus 10 devices, as well as the Samsung Galaxy S4 and HTC One Google Play Edition devices.
