Sony didn't have much success with the Xperia Z2 Tablet although the tablet had impressive specs and design. The problem for that was Samsung's Galaxy Tab lineup and Sony is determined to strike back with the Xperia Z3 Tablet, which could be announced at IFA 2014.

The sequel to the Xperia Z2 Tablet has been caught in a listing on the Indonesia Postel website, with a model number SGP621. The first Xperia Tablet Z has a model number SGP321, the Xperia Z2 Tablet carries the model number SGP521, so it means only one thing - Xperia Z3 Tablet.

The tablet is also rumoured to sport a smaller display than its predecessors, which could be somewhere around 8-inch. With IFA 2014 event approaching, we could know a lot more about the Sony's new tablet.
