According to German website mobiFlip.de, O2 in Germany is planning on launching the Motorola DEFY+, an updated version of the current Defy. The only changes we know of right now is a upgraded 1GHz processor from the 800MHz in the current DEFY and Android 2.3.3 Gingerbread instead of Froyo. Everything else seems identical, including the design.
To be honest, those were the only two drawbacks of the current DEFY and we're glad that the new model addressed those.
