Android 4.2 codenamed "Key Lime Pie" is being sneaked onto devices, according to Android Authority who noticed they were seeing visitors to their website from devies Google Analytics said were running the new Android 4.2 OS.

The devices Google Analytics picked up running Android 4.2 were the Nexus 7, Samsung Galaxy Nexus, Sony Xperia Arc S and the Samsung Galaxy Y - so fingers crossed we should see Android 4.2 on these devices shortly after its release.

Two other names appeared also, Occam and Manta, who are rumored to be a Motorola smartphone and tablet, respectively. Of course, this is unconfirmed at the moment. Android Authority have reported that the Google Analytics data shows that visits to their site from Android 4.2-based devices has happened since August, which would show that the testing of Key Lime Pie has been going on for two months.
