I think you underestimate the uniqueness of the Filmation Evilseed and the generic look of the MYP Evilseed. Honestly, 200x Evilseed is completely unremarkable.
The Filmation episode is also one of the best of the series. It would be a shame to not have the figure to mark that quality.
All that said, it's up to Matty. I hope they stick to their word on 200x, but they've demonstrated repeatedly that MYP designs are going to creep into this line from time to time.
