In either case, we expect November 3rd to be the opening of the floodgates for the Android 5.0 Lollipop update for the Nexus 5. But considering the batching process, it could easily be mid-November before you finally see it on your phone (if you're one of the unlucky ones). But never fear, as soon as the OTA starts rolling or the factory image becomes available, the internet will melt down – so there's no chance of missing out on knowing all about it when it does start to happen.
