RA-22 Sideswipe & Sergeant Epps
RA-23 Arcee
RD-17 Long Haul

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?
Can't say this wasn't expected.
But could still be something entirely different until we get some pictures.

Encore Skids is a nice opportunity for those who don't have an original or earlier reissue.

It's also interesting to note a black version of Alternity Megatron in the schedule.
