I voted for Thrawn, since as cool as it would be to get a Snow Bunny Padme, I'd rather see a true EU character than a film character in an EU outfit. I know that Thrawn will be "boring humanoid alien in military uniform" but I justify it as saying it will be the first true Expanded Universe character as a 12" figure.
Will I actually buy any of those six figures listed? Probably not, to be honest. I'm kind of getting out of 12" collecting in terms of characters I'm not really passionate about, and none of those are characters that I'm particularly fond of (Padme excluded).
That said, I think they made some very good choices of who to pick from, although I must say I'm disappointed there were no "Ken Palpatine" or "Horse Pilot" options.
