So, how many figures were shown that weren't released from this line? It seems like there were more announced than there were released at this point. This is what I can recall off the top of my head:
-Clone Trooper (Geonosis Captain; from SDCC)
-R2-D2 (Invisible Hand; from SDCC)
-Darth Maul (packaged samples exist)
-Luke Skywalker (X-Wing Pilot; packaged samples exist)
-Clone Trooper (Utapau; from Hasbro's site)
-Han Solo (from Hasbro's site)
-Darth Vader (version 2; from Hasbro's site)
-Snowtrooper (from Hasbro's site)
-Jango Fett (was up for preorder at many sites)
-The Battlestar Galactica character (not SW, but announced officially several times)
Then you've got the last two waves of figures which, for all intents and purposes, might as well have remained unreleased considering how little they were seen (501st Clone, IG-88, Grievous, and Threepio), and four figures that WERE released (Fett, Vader, Bossk, and the ST).
So, out of a grand total of 18 figures (I'm not counting variants), four were released in abundance, four were released but impossible to find, and 10 were announced and will probably never be released.
What killed the line? High prices? Poor availability? Lack of character selection? Timeliness of releases? Fox News? All of the above? None of the above?
