Sorry, but I believe you are wrong.
Until Mattel purchase the rights and start releasing FILMation characters they have certainly not "come through and made this line what every MOTU fan has always wanted..."
MOTUC will fall well short of expectations if FILMation characters are not produced. The FILMation toons (MOTU and POP) were so important a part of many fans love of MOTU. Leaving out FILMation characters would be like ending the line without a figure of the Sorceress or Prince Adam.
The promise of this line will never be realised until we see figures of Shadow Weaver, Scorpia, Imp, Fang Man, Lizard Man, Uncle Montork, Shokoti, Kothos, Octavia, Batros, Strongarm etc.
Without FILMation there is a hole in the MOTUC mythos big enough to smash a planet through!
While it is cool we are finally seeing vintage prototypes incorporated into the toyline, and mini-comic faves like the Goddess, plus MYP toon characters, these do not make up for lack of FILMation MOTU/POP characters.
