We only just had the Devastator teased, and now we get Defensor teased with a silhouette... with a leg that looks like it could be a motorcycle (Groove).

As I had speculated in the UW Devastator topic...

if this gets numbered as UW-03 because it is being teased before Defensor, I wonder if TakaraTomy are pushing Devastator ahead of the release of Defensor, to give them more time to be able to use the rumoured Motorcycle mould for Groove (if the rumours are true about Technobots being one of the first of the second series of Combiners... which should be out by the end of the year by Hasbro).
Based on the timing of Superion and Menasor, by the time Defensor comes out in Japan, it should be close to the end of the year, and we should have the first wave of the second series of Hasbro combiners by then... which is rumoured to include Combaticons and Technobots.
