What's with you and anime? Seriously, the chances of an anime winning Best Picture in the Oscars is 1 in a million. I don't recall any of the anime you listed being in American Theaters.

Anyway, I enjoy anime myself, but I don't treat them any higher then other movies. Anyway, to answer your original first question about Ghost in the shell 2. No, it's unlikely it'll even get nominated. I never watched it, nor know that was out in the movie theaters.

To be even considered an Oscar nomination, a movie or animation should be viewed in theaters nation-wide, as far as I'm concerned. Why Spirited Away did so well, it was brought over to America from the folks of Bueno Vista, translated by American (voice) actors, and made an impact.
