IMO MP10 is a nicer toy as a play set and interactivity with the MP cars, but as a stand alone toy MP1 is the better action figure. I can't really imagine what they could do to significantly improve over the existing MP1 and MP10 figures. Even making it look more show-accurate is merely a cosmetic variation.

MP36 excites me not really because it looks more like the cartoon, but because it just looks like a better toy (although MP5 still looks to have a more accurate looking gun mode). It looks to be a significant improvement, and hopefully one that is more intuitive to transform and fun to play with (my two main gripes with MP5). I have no gripe with MP1 or MP10.
