@Agent P fan - It's really hard. Though my best bet to get the Best Animated Feature is The Croods, Monsters University, and Frozen. Here are some of my reasons.
The Croods - Read on some articles earlier this year saying that it's an early leading contender for Best Animated Feature.
Monsters University - Knowing the track history for Disney's Pixar films, it would probably most likely get the nomination nod.
Frozen - With early acclaim from film critics even though the film is not out yet till the 27th, Frozen will most likely get the nomination nod as well. It also has this feel that fits well similarly with earlier Disney Animation films of Beauty and the Beast and The Lion King.
