Just Batman for me. Only other pieces I may consider are killer croc and Bane. We'll see how long they take to come out and what the price will be like.
It could be those that pre-ordered Harley are visiting this section more frequently but that's a high percentage ordering the exclusive. Sideshow is going to have no problem setting the ES at 1500 from the look of things.
I think Harley Quinn has the better sculpts of the two female statues, but am getting neither. Catwoman is be the only female Bat-villain important enough for me to consider.
