I picked up everything new at gencon. This includes ordering the arcanist and 10 thunders box online while there. With that said, some models, no they aren't as good as we have seen in the past. However overall I have had a great experience with these plastics so far. My only gripe is with the nightmare tree this year, only because mine doesn't fit inside its core roots well enough and i have to green stuff a huge chunk of the tree, though upside it is taller. Also the ropes snap easily, though that is to be expected with something so tiny in plastic.
There will always be something to dislike about a product, no one and nothing is perfect. You have to take the good with the bad. However I would advise opening the miss terious box and checking her out, I have yet to see one of her that i didn't think had great detail.
