As to whether it will survive? Who knows? No one really knows if it will as the whole prepainted minis and evolution rules set is mostly untested. There are similar games, namely the method that Mongoose is using is similar to the Heroscape board/minis game marketing method, and that's been very successful even in the casual gaming market.
Also, there were rumors that the Coven, or some other 5th army, would be coming out sooner rather than wait for the usual 4 armies at every new release. The thinking was that skinnies aren't too popular and they can't make too many changes since the look is established (based on a cartoon kids show, of which the in house artists didn't like the skinnies), so a 5th army would be the real alternative for those who might want an infantry army, but not like human MI, or the weirdness of skinnies.
Sad to say, about the above minis, I don't like that that much. Too shiny. Maybe a coat of matt varnish, then some brush on gloss on the area where you want shinyness will help.
