Android 4.2 for Asus Transformer tf300t I bought an Asus Transformer tf300t tablet. It runs on Android 4.1. 

I really need the multi-user feature of the Android 4.2.

I read that Asus will provide an upgrade for all the Transformer series to Android 4.2, but there isn't any official announcement.

Should I wait for this hypothetical upgrade or install a CyanogenMod ROM right now?
You can install Cyanogen now, and in the event of an official update, go back to the stock Rom.
