Nexus owners may have a reason to stay up tonight, as a couple of Reddit users report that Android 4.2.2 has begun rolling out to the GSM Galaxy Nexus and the Nexus 7. This is a release Google was rumoured to start shipping in Brazilian Nexus 4?s over a month ago, but nothing ever came of that assertion.

The report mentions that the update is being rolled out to select devices, carrying the JDQ39 build number. 

The update comes in at little over 46MB and considering the fairly significant size may feature plenty more under-the-hood changes. Android 4.2.2 is currently rolling out in waves and will likely hit the Nexus 4 in the following days if previous deployments are of any indication. For Galaxy Nexus owners there is an OTA Android 4.2.2 update file that can be manually downloaded and installed afterwards using ADB Sideload in the recovery.

Unfortunately, there’s nothing too exciting to report, as the update provides mainly performance and stability fixes, and allegedly fixes a bug related to streaming music over a Bluetooth connection.

It’s not surprising that the update doesn’t deliver many new features, as Google is widely expected to announce the next major release of its Android mobile operating system, which is likely to be named Android 5.0, at its Google I/O conference in May.
