Android 4.2 is official! So is the LG Nexus 4! But what about all those current Galaxy Nexus and Nexus 7s out there? They're going to get an update to Android 4.2, right? Most certainly. And we're willing to bet the Nexus S goes along for the ride as well.
One thing we don't quite know is when, but we can take a pretty good stab at it. The LG Nexus 4 goes on sale Nov. 13. Don't expect an over-the-air update to push before then, and chances are it'll be at least a few days after that, too. We'll also probably see the Android 4.2 code drop into the Android Open Source Project repositories before any OTA update takes place.
In other words, get your finger off that update button, folks. More than likely you've got a couple weeks of waiting ahead of you. (Though if Google wants to push the button early, you won't hear us complaining.)
