Google has silently added the factory images as well as binaries based on Android 5.0.2 release for Nexus 10 and the Wi-Fi version of Nexus 7 (2013) tablets on its developer website. With factory images out now, the owners of these two devices can expect to see Android 5.0.2 OTA update soon.
The OTA update will most likely arrive in the next few days. To remind you, Android 5.0.2 includes fixes for most of the bugs that have been identified on these devices since the Android 5.0 roll-out.
There is still no word on whether and when Nexus 4, 5, 6, 9 or the cellular versions of Nexus 7 (2013 & 2012) tablets will be getting the same update.
To remind you, factory images help users in restoring their devices to the original software state if case of any software mishap.
Nexus 7 (2012) too has got it now.
