Toy aisles in general retail stores have always been a fickle beast with less emphasis placed on what actually sells and more emphasis placed on the "hot" toy of the moment. Star Wars, by and large, sells as good, if not better, than any other action figure line in the AF aisle, yet it consistently gets the short shift unless there is a movie in the theaters.
With Star Wars (at least in the retailers I've been in over the past 10 years), toy departments seem to not like the fact that they have to stock them at all. They are consistently the worst stocked action figure line in terms of assortment and stock status in general, the sections are, mostly at WM, in a constant disarray, and I've seen more than one toy department manager roll their eyes when SW is even mentioned. My local WM has a Grievous Bodyguard that was completely ripped off the card and they still
have the card itself (no bubble) hanging on the pegs with the bubble laying on the shelf below, with a fresh WM price tag of 5.88 attached to it.
Star Wars was, by all reports, supposed to have had the "feature aisle" at WM to itself until the beginning of August, but by the beginning of June in most places, it had already lost half its space to the Fantastic Flop and the 50 different Batman figures. Neither of those lines sold well AT ALL around me (the fact that there was no Dr. Doom in the FF line until well after the movie was released still makes me scratch my head) but they continue to have more shelf space at WM than SW, which sells rather briskly unless it's a Neimoidian or Clone Pilot.
As for the Final 12, if I ever see them on pegs around me, I'll be shocked. I have yet to see a Shocktrooper or a Green Clone Commander on pegs (the only reason I have one of each is thanks to you, Slothus), and anything past 44 has been something of a chore for me to find. A case assortment where the new figures are all packed 1 per case in the final run of figures is not going to be fun and I have a feeling I'm going to be doing a lot of begging on here and hope that someone will take pity on me.
I'm going to be the eternal pessimist and say that by the time the 2006 Saga Collection is hitting en masse (relatively speaking) in January, WM will have SW back to its usual 6 pegs of figures and a shelf full of lightsabers, while there will still be 20,000 Thing feet taking up space.
