I just popped over to Hivewire's Forum and read where Hivewire is indeed coming out with an official set of morphs and visemes for Dawn. So that concern is being addressed. I think the best we can do for now is to wait and see how much they help Dawn become a better figure. V4 didn't become the most supported figure in just three months, and Dawn won't either.

I also seem to recall that DAZ's solution to addressing the same problem when V4 first came out, that being too little content, was to put V4's head on V3's body..
