Umm, so yeah, Google just posted Android 4.4.4 factory images as build KTU84P.
We are seeing files for the Nexus 5, Nexus 7 (2013) WiFi, Nexus 10, Nexus 4, Nexus 7 (2012) WiFi, and Nexus 7 (2012) Mobile.
The new 4.4.4 binaries are there too.
I would be lying if I said that this move wasn’t surprising. We just got an OTA update on almost all Nexus devices to Android 4.4.3 a couple of weeks ago. I would imagine that another OTA update is imminent. Any guesses as to what it will fix?

Update: My Nexus 4 is now running Android 4.4.4. So far, not seeing anything new in particular.
Update 2: According to Sprint, the update is nothing but a security fix.
Update 3: If you are prompted with an OTA file, don’t forget to grab the URL of the file.
