Wow, it's being waitlisted after only an hour of being available? That's pretty quick, but they said it was limited to 1,500 pieces. Did they give you an option for the nonexclusive figure? At $90+ I don't know if I would want the nonexclusive, and I'm also glad I only go for select figures.
Yup, unless I did something wrong, the only way I could get the exclusive was to wait list. They did have a pre-order for the regular version available it seems. However, for $90, I want the exclusive version (as you supsected). If not, someday I'll pick one up on eBay.
I've gotten every SW 12" that I ever put on wait list (3 of them over the last few years), so you should be in good shape.
