I think these plastics look respectable. I don't know where you get the notion that the old Necromunda figures were not fussed with too much detail... the metal escher gang have a ton of bits and bobs on them, except for maybe the juves...

They aren't going to make a decent profit selling a rehash of figures from 25 years ago. It has to be modernized if they want to expand their customer base. I am not privy to their numbers, but I assume that bringing in new markets is more profitable than pandering to old diehards that may or may not buy something...

If LAF has taught me anything, it's that a proper paintjob can make any motley crew of figures seem cohesive. I see no reason why this cannot be the case again, barring glaring differences in scale.
