The 4.4 KitKat factory images are now finally available for all supported Nexus devices. This includes the Nexus 7 2012 (Wi-Fi), Nexus 7 2012 (3G), Nexus 7 2013 (Wi-Fi), Nexus 7 2013 (LTE), Nexus 10 and Nexus 4.
Unfortunately the Galaxy Nexus has now surpassed it's 18 month support period.
R.I.P Galaxy Nexus...
This is great news for any power uses that can't wait for the official OTA but flashing the factory image will wipe all user data so if you are wanting to update without waiting you might be better off ADB sideloading the OTA update zip.
As a word of warning the factory tarball download for the 2013 Nexus 7 Wi-Fi is currently only containing scripts and missing the important images so for now avoid that download.
