It seems that the upcoming MP-13 Masterpiece Soundwave and his cassette-bots is sort-of following MicroMan release back in days 80s
MP-13 Soundwave + Laserbeak
Pretty much MC-10 CassetteMan, but MC-10 actually came with MC-01 Red Micross (Rumble)
instead of MC-03 Condor
MP-15 Rumble & Ravage
Hence MP-15 is needed, and MP cassette mold is complete for me
MAR 2013
MC-01 Red Micross / MP-15 Rumble
MC-02 Black Jaguar / MP-15 Ravage
END 2012
