Sony may have demoed early Android 5.0 Lollipop builds on the Xperia Z1, Z2, Z3 trio but it’s the Sony Xperia Z Ultra GPe that is getting the coveted update first. GPe – short for Google Play Edition – is a line of purified flagship devices from several makers, like a branded Nexus line.
Some lucky bloke on the Android Central forums already downloaded the system update, weighing in at 397.3MB it requires at least 500MB free to install (that’s not much, considering iOS 8 requires 4-5GB).

The update introduces a "bold new visual style" (Material Design), improves performance and adds new features. Among them are notifications on the lock screen, interruption controls for the notifications and Smart Lock (disable the secure lockscreen when connected to certain Bluetooth devices or NFC tags). The battery saving mode has also been improved.
Again, note that this update is for the Sony Xperia Z Ultra Google Play Edition, the one with Xperia software is still waiting (but will certainly get the Lollipop update).
