I think some of their rumor lists in the last couple years are pure bunk and wishful thinking by someone... Just my opinion. You can always tell when Curto got something himself, and when he got it from "a source" that seems to have turned up semi-recently.
Personally, if I were to pick 2 Cantina dudes I want (other than Bom Vimdin who's my #1 right now), I'd go with Dr. Evazan, and Garrouf Lafoe... I love aliens as much as the next guy, but I'd like to start seeing some human characters getting done.
I'd love both Saurin then, Yerka Migg or some Tonnika Sisters.
Right now though, besides Vimdin, I'd say Ponda, Dr. E., and Garrouf Lafoe are my top 3... Dr. E. and Lafoe are my top 2 though.
And behind them I'd like to see some of the goons that SE Jabba takes along to the Falcon. The pointy hat guy, the big bearded guy, and the mustache guy w/hat & goggles would be the 3 I'd most like to see... Those guys have gotten no love, but they look like badasses.
