I'm not disinterested, but I am frustrated... What is new isn't out in any quantity, there's no abundance of figures I want (Sandtroopers and Death Star Gunners at the moment, and the Endor Rebels who I've yet to see). New stuff seems in short supply...
That hurts my ENJOYMENT of things, but as far as the line goes I am even considering pre-ordering cases actually. I haven't done that in a while really. The repaints and stuff though have me very interested and the early '07 figures really impress me for the most part.
The things that kill my interest are when figures fall short of being really high quality in my opinion and it's no secret that a lot of that lies in when a figure lacks articulation at a point that it should have it irregardless of who the figure represents. Next is price... I don't mind $7 for really great figures, but for Derlin, Veers, Sora Bulq... I really start to question what I buy, and I definitely start cancelling buying "extra" of a lot of these. I lack the fodder of course then, but $7 for a figure I'm not happy with is only acceptable to get it and review it and put it in my collection.
Add then not being able to find what I actually wouldn't mind paying the rape prices for and I definitely have a lot of frustration with the line right now... I'm actually looking forward to camoflauge battledroids though, and the Clone repaints are cool... I can deal with this stuff at the end of the year, I just worry it'll be as hard to find as anything else since last year is the precedent for this situation, and finding the final figures of ROTS was a huge pain for many (myself included).
I think the more classic product for '07 we see, the more people will come around though... There's a lot of prequal stuff so far kicking it off next year and I think classic stuff may rejuvenate some interest in those fading.
