LG G Pad 8.3 Google Play Edition Owners, Come On Down: You're The Next Recipients Of A Lollipop OTA Update
Naturally you'll need a stock recovery in order for the OTA or an ADB manual flash to take, and any extensive modifications of the stock system (including root) are going to block it as well. Once you've got everything up and running, don't be surprised if you see a few bugs - the initial Android 5.0 updates for Nexus phones and tablets haven't been completely smooth.
GPE devices generally get very quick Android updates, but they're still a bit unpredictable, so we won't hazard a guess as to when the GPE phones will be getting a taste of Lollipop. Hopefully those users won't have too long to wait.
