Sprint has announced on their website that starting 4/14/2014 Google will start rolling out Android version 4.4.3 to Nexus 5 devices. It can take up until 4/21/2014 for the roll out to complete and until 4/28/2014 to reach all devices. So within the next 2 weeks we should all be happily enjoying this update. This update includes the Spark update for Sprint and Misc. bug fixes.
Edit** So Sprint pulled down the original post because they said a bug was found by Google. Now we wait...........
