I'd likely buy all of them, but I know without a doubt that I would buy Rorschach, Nite Owl II, and Ozymandias. Depending on what the sculpt looks like, I'd probably buy the Comedian. Not so sure about Jon; I'd have to really be wowed to spend $150+ on him.
I don't care how long it takes - if HT puts out anything Watchmen, I'm buying it. :D Although I must admit that I'm very anxious for a good Rorschach.
I'd also really love a 1:6 Ozy, but that seems more like a pipe dream than anything. :(
I don't know - this newcomer (have never seen any Terminator movies before this one) was definitely converted after seeing Salvation. :lol
I'm definitely buying the HT Marcus Wright & HT John Connor. Loved both of the characters in the film.
