The reason Oscar now go with 10 BP noms instead of the traditional 5 is because of the snub they did to TDK and Wall-E a few years ago. That created a backlash and the Oscars handlers thought that by expanding the noms to 10, they won't leave any fan-favorites out. It is probably also a scheme to help the rating since they believe many fans of the BP noms will tune in to see if their favorite film will win the big one, although I think it will probably be awarded to either The Social Network or The King's Speech. Unfortunately, Inception has a long shot to win this one.
