That's gonna be expensive for some of us, as JP prices are always high, and the paint apps on these will make them expensive too.
I see that a couple are from the "Trilogy" series that never happened, which was to have some redecos, like the Soundblaster Soundwave that appeared on ebay as loose figures.
Since these are from all four movies, it really is a "Movie Universe Line".
NOTE that the Japanese name for "Age of Extinction" is "Lost Age", and these are just advance toys (coming out early May, instead of the main line that is likely to be out in June in Japan, as the May 17th embargo doesn't apply to them since they don't have the Hasbro toys).

TF1 DLX Protoform Optimus Prime - Gen1 redeco & new weapon
TF2 VOY Optimus Prime - metallic deco
TF2 (HFTD) DLX Battle Blades Bumblebee - metallic deco
TF2 DLX Payload - retooled into TF1 Dispensor
TF2 LEG Devastator - minor redeco to make it even more movie accurate.
TF2 DLX Sideways - retooled into TF3 Dino/Mirage
TF3 DLX Starscream - in TF1 colours & new weapons
TF3 DLX Jolt - in TF2 colours
TF3 DLX Ratchet - similar to the previously cancelled white with red redeco
TF3 DLX Soundwave - similar to the previously cancelled black redeco
