Back on Halloween, Google promised that proprietary binaries and factory images for the Nexus 4, Nexus 7, and Nexus 10 would arrive shortly after devices received their OTA updates. Even though some OTAs haven't even rolled out yet, as of a few minutes ago, all modern Nexus devices now have Android 4.4 KRT16O factory images and drivers available for download.
This means you can flash stock Android 4.4 onto any supported device, even if an OTA either wasn't available yet or wouldn't work for some reason.
