Over-the-air updates to Android 4.2.2 are rolling out now to the current crop of Nexus devices. Reports first started trickling in on Reddit about the GSM Galaxy Nexus having its update waiting. And more recently, news from Android Police, XDA and elsewhere indicates that Nexus 10 and Nexus 7 users are getting these updates, so it looks like we're in the midsts of the 4.2.2 roll-out.
No news on the Nexus 4, interestingly enough, but we'd assume if the rest of the Nexuses are getting it, the N4 will be on that train too. We're of course not sure what all this update has in it, but we're not expecting much more than bug fixes considering it's just a x.x.1 jump. After updating our own Galaxy Nexus to 4.2.2, there don't seem to be any immediately-noticeable changes.
So have at it folks, start checking your devices for that update. If you're into manually updating (advanced users only), we've got direct OTA package links for the Gnex and Nexus 10 after the break.
