These both look so finished that I wouldn't be surprised if they show up on preview night tomorrow! Hopefully the pose of Batman is less awkward than their Arkham Asylum Bats. It looks like it'll be more a prepared for battle pose, which could work. It's promising though! The suit looks like it'll be fantastic.
As for Joker, the pose looks spot on...love the addition of the card...just works really well. I'd have to think the EX would either be a swap out smiling head, or another card, maybe with a scratched out Bat on it, or something. The usual crazy Joker card.
I'm going to stick with the Prime 1 line at this point, with Batman ordered, but if these sculpts turn out this well, then they could end up being two of the more accurate movie PFs out there!
