On the front of Legacy not selling well/collector interest is down I would like to point this comment out from Hasbro in their answer to SSG:
Last Fall, however, we saw a change. There was an overall reduction of collector dollars in the action figure collecting hobby to which Star Wars was not immune, and we saw this on a more granular level in the sell-through of purely collector-target figures. While the hero figures (Obi-Wans, Anakins, Lukes, Vaders, troopers, etc) continued to do very well, the collector figures really started to struggle compared to all past years. This resulted in a need to recalibrate our release levels for these figures, since without that recalibration the normal releases we would make on purely collector figures would now be too large for the current collector market to bear, pegs would really start to back up, and the whole Legacy/Droid Factory figure flow would grind to a halt - in short, a disaster, unless corrective measures were taken.
I don't really think this is fair to put on the collector's shoulders. In my area from around the time the new figures hit the shelves in July until Novemember that's all that was available, aside from TCW animated figures which sold well. Now wave 2 moved very well and the main charcters from the first wave sold well. My area then got bombarded with Saga figures. So of course the "main" characters sold well that's really the only choice we had in my area. It really seemed that there was at least 5 Yarnas apiece for every collector in the known universe. So I think it's a smart move by Hasbro to cut back on the production numbers of collector-oriented figures, just don't put the blame on the collector's shoulders when crappy distribution of newer figures played a role in what a collector could buy.
