Very clearly these are a form of Chibi-fication as opposed to de-aging (I mean, come on, people, they're still modeled as fully developed women, merely with diminutive proportions) The full fault here is in the unfortunte Engrish title which people are taking to ridiculous ammounts of "worst case scenario".
I'm jsut glad painted prototype pics have surfaced to reduce the silly ammount "outrage". (I'm pretty sure if that name had not been revealed and we'd just gotted "hey look at these cuti-fied Gundam girls figures, there'd be nowhere near as much venom here)
