One moment please! Everything in 7ed will be plastic? Those models are from starting box - I mean they are simplified version? Or they are the official version for O&G ?
As for the paintjob, I have no official source or something, but I think they reduce the quality of their published paintings on purpose, not to frighten away newbies. If you check the latest Black Gobbo, there is a masterclass painting section in it. Noone (of us) can really say that this is really masterclass painting... They are just tabletop quality in my eyes.
it's great that gw finally released 100% plastic cavalry;
and about fanatics... well... imo these ones look crappy actually goblins models I like the most are metal ones from 5th warhammer edition...
