RE: the OP, yeah Bosk, Disney only seems to carry lots of stuff that sells well. While it is a mixed bag sometimes, with surprises here and there of what's available (at parks), generally the same franchises are overpopulated. Case in point, my favorite movie ever, WallE, has jack for anything really substantial, and basically has been that way since it came out.
The unfortunate thing is Cinderella, Snow White, Cars, Sleeping Beauty, Toy Story and so on dominate their merchandise, licensed and official.
