According to a tweet from Mobile-Review, Motorola is working with Google on the release of Android 3.0 on a tablet device called the MOTOPAD . Mobile-Review is the home of mobile authority Eldar Murtazin, who tends to have a line on these sorts of things. The tablet would be a 7-inch unit, and would presumably be the only one with early access to the tablet optimized version of the operating system.
This wouldn't be the first time Google has turned to Motorola to launch a new version of the mobile operating system. About a year ago, Android 2.0 debuted on the Droid bringing a number of new features including CDMA support and higher screen resolution. We can't say for sure that this is real, or when it would show up if it was, but it's about time Google got in the tablet game officially.
