Oscar predictions?

Obviously, this will go into the Academy Awards as the favorite to win both Best Picture and Best Director. I'm also assuming Eddie Murphy will get recognized for his performance, but what else? Here are what I think it will be nominated for.

Best Picture
Best Director
Best Actor (Murphy)
Best Supporting Actor (one for each of the dudes in Starbucks)
Best Supporting Actress (Kerry Washington)
Best Original Screenplay
Best Cinematography (it was beautiful)
Best Original Score (it too was beautiful)
Best Art Direction
Best Film Editing
Best Sound Mixing
Best Sound Editing

My only concern is that each of the supporting actor nominees will cancel each other out and the prizewinner will be an inferior performer from an (obviously) inferior film. I personally wonder if I'm underrating it a bit; I think the visual effects guys have a good shot at getting the nod.

Your thoughts?
