Google has started rolling out the Android 4.2 update to its Nexus devices, but that doesn't mean all Android device makers are ready to do the same thing for their existing tablets and smartphones, especially since some of them are still busy deploying the previous Jelly Bean version.

However, it looks like Asus is already working on updating some of its Transformer tablet versions to Android 4.2. An ETA on the roll out of the firmware update is not available yet, and we have no idea what models will be supported, although it’s more than logical to assume that those devices currently running Android 4.1 or later will also be bumped up to Android 4.2 also.

But it looks like an Asus customer representative confirmed that Asus is working to Android 4.2, without actually providing availability details. A rough Google translation from Dutch blog Android Planet reads:

Asus has confirmed that the Transformer Prime TF201 update to Android 4.2 Jelly Bean is received. Reported that the Customer against Asus Android Planet reader Erik. “When Google launches a new Android version, it will take a while before we update our customers spread. We are currently working on the development of Android 4.2 for our tablets. The update will naturally follow and you get an automatic notification on your tablet if it is available, “said Asus.

We’ll be back with more detailed information regarding Android 4.2 updates for the handset once we have it.
