I probably would have become more interested in superheroes as a kid if something like this existed! I also like how the costumes aren't so bathing suit-like, it makes cosplaying a lot more approachable, as well.
I don't know if these are prototypes or the finished product, but I really like what I see. I definitely want Wonder Woman, and would probably pick up the Batman characters. Not really crazy about the rest, though. But I like that so many of them are wearing pants! I always thought that crimefighting in those skimpy leotard-type outfits looked so uncomfortable, like they'd get a wedgie at any minute.
There will be more characters than these, of course--apparently some of the male characters like the Green Lantern will be present--and lots more merchandise, including some action figures. Merchandise is supposed to start rolling out later this month (although that can always change), so I'll be keeping my eye out!
