To help complete the 1986 Movie roster in "Generations" style toy form over this financial year, the Combiner Wars Devastator is an obvious choice... and even though it was mentioned a couple months ago that it is supposed to be released through Amazon around January (including here in Australia), the Hasbro Pulse website have just listed it for pre-order, for release January 15th, for US$150.
The box and toys should all be identical to the original release... even though it would have been better to have them use the Japanese version, which had some extra joints and individual weapons.
