Via that link, they also have Batgirl as the preorder for the Catwoman bombshell statue.
Although you guys may be right that this is the Arkham Catwoman, the boots definitely have a vintage Victorian look to them and the garters and lace appear to be quite prominent so they definitely had me fooled.
It most certainly IS the Arkham City Catwoman. I already have it on preorder with DCBS and they have it listed properly. I'm collecting the AC line so when DC collectibles announced this piece I was very excited. For anyone interested in the piece, there is no ifs, ands, or buts about this being an Arkham City piece.
