A very late addition to the TakaraTomyMall site as an exclusive is the Siege Skywarp boxset (yes, another Siege toy to go with Ratchet that they are finally releasing in 4 months time).
This is the Phantomstrike Squadron set, which has Skywarp, Fracas, Shrute and Terror-Daxtyl, for release in January (same time as Siege Ratchet), for 7150yen (about AU$100).
