Charming conversation...
It's ok to be annoyed with Hasbro over exclusives like this show's McFigures... Brand new figures, hottest sub-line to the basic figure line in ages really, one likely available afterwards but the other figure being completely up in the air as to whether or not it'll be a tough one to track down... THere's some pretty valid reasoning there to be "pissed off" at Hasbro.
Whether you can track down help... It's best to ask early. C3 Vader was EASY to get ahold of, and it was EASY to get stuck with them too after the show... THese, I don't think will be so easy to get stuck with but I'm truly hoping our folks going (who work for the site and who just frequent our boards here) are gonna be able to help out as many people as possible get these McFigures as easily as possible.
Poddie, see if you can get on the "I want a figure list"... I can't recall where it is, but it's around here somewhere (check the C4/Conventions part of the forums, I think it's there). I think someone will help you out as long as you cover cost + shipping.
