Well for those that said Buster Prime looks of masterpice quality, its probably b/c he was MADE by the guy in charge of all MP's except MP-03. Here is a translation of the Buster Prime interview with designer Hirinori Kobayashi. He mentions why they made EZ collections Devastator.

He also mentions a little hint about the NEXT Masterpiece

Hirinori Kobayashi came up with the idea of Buster Optimus Prime and designed the muffler > gun transformation. It was also difficult to recreate the exact hue of purplish blue with the plastic, which he considers as more film accurate.

He belongs to domestic product team, and for ROTF he has been mainly responsible for some modifications of the products aimed at Japanese release.

He explains the reason of developing EZ Devastator as, "While RD-16 Devastator is impressively huge, its strength is in gimmicks. I thought Japanese TF fans might not be satisfied with it, since even 25 years old (G1) item achieved Robot > Vehicle > Combine modes."

He was in charge of all Masterpiece products, except for MP-3. He again hints of the new MP next year 2010, which has a significance to Transformers. ("2010" is s Japanese title for G1 season 3.)

One of his favourite (of the products he developed) is Rescue Hero Gobots Chopper!
