Hello KRin,
PIXAR and Disney are re-evaluating their relationship. It's always been a rather tense marriage; Disney likes to suck properties dry, producing ever more mediocre sequels to hits, and periodically removing films from circulation to artificially build up demand. PIXAR has needed Disney for it's distribution prowess, and has enjoyed a level of autonomy under the Disney umbrella they might not have enjoyed with another studio.
However, Disney's animation division has been in a steady decline; recently, only "Lilo & Stitch" has managed to break out. Aside from that film, only the PIXAR movies have been worthy of the Disney canon AND generated huge revenues, but the cultural differences between PIXAR and the House of Mouse are probably too great for the association to be sustained. I'm sure PIXAR would love to put up a terrific "Nemo" page, but probably couldn't do so without having the Disney marketing hacks breathing down their necks.
Good Lord, living in Los Angeles has finally proven useful. Only took three years.
Yours truly,
Clem
