With Android 4.4(Kit Kat) now officially announced, we all want to know when we can get it. Ed Heyl, who appears to be the new JBQ has announced that the Android 4.4 – Build KRT16M – is now being pushed to AOSP with Factory images and Binaries for the Nexus 5 due up on the Nexus Factory images page later today.

Today, Google took the wraps off the Nexus 5 and the Android 4.4 KitKat release. Now we’re happy to announce the matching open source release. You can read more about what’s new in Android 4.4 KitKat on our developer site.

We are in the process of making two new branches available:
kitkat-dev for kitkat open source contributions
kitkat-release the kitkat release build (KRT16M) for the Nexus 5–which will be tagged with android-4.4_r1.

We are making the proprietary binaries and factory images available for the Nexus 5 today as well.

In the coming weeks, other Nexus devices (Nexus 4, 7, and 10) will receive their KitKat update, and we’ll make those proprietary binaries and factory images available at that time.

We will reply to this thread later this evening (PST), when everything is ready.

Enjoy!

Unfortunately the Galaxy Nexus seems to not be included, so maybe it’s time to head over to eBay or Re-Gadget and see what it’s worth. We’ll update as soon as the factory images appear.

Update: The Nexus 5 ‘Hammerhead’ Android 4.4 (KRT16M)Factory Image and Binaries are now available on the Factory Images page. The images are being picked apart now with APKs for a lot of new Apps surfacing around the net.
