Hobby Search has listed the following Transformers items for release later this year(mostly Revenge of The Fallen figures).
October:
RA-21 Bumblebee & Sam Witwicky
RA-22 Sideswipe & Sergeant Epps
RA-23 Arcee
RD-17 Long Haul
RD-18 Grindor
Encore18 Skids
A-02 Nissan FAIRLADY Z Megatron/Diamond Black
November
RA-24 Buster Optimus Prime
RA-25 Skids & Mikaela Banes
Buster Optimus Prime is described as having lights and sounds, and mech-alive gimmicks. It is also listed for 8,190 yen with a discounted price of 7,371 yen(which is the cost of the leader class figures). Could this be a retooled version of the leader class figure with blasters, as shown in the beginning of the movie and video game? Or could it in fact be, a set of all new voyager class, Optimus Prime and Jetfire figures which can combine?
