Best Animated Feature

Cloudy with a Chance of Meatballs, Phil Lord and Chris Miller

Coraline, Henry Selick
A young girl discovers a new world featuring an idealized version of her dysfunctional family life — and some spooky little secrets as well.
Fantastic Mr. Fox, Wes Anderson
Farmers band together to get rid of Mr. Fox (voiced by George Clooney) and his family (Meryl Streep is the Missus).

Ponyo, Hayao Miyazaki
A five-year-old boy and a goldfish princess develop a close bond.
Up, Pete Docter
A man in his late 70s takes his house and a young stowaway to the South American jungle.
In case there are 16 or more animated features being considered for the 2010 Academy Awards, the category automatically goes from three to five entries. There's a chance — however slim — that'll happen this year. So, just in case, I've listed five films.
In addition to those five, other potential Oscar 2010 contenders are:

Shane Acker's post-apocalyptic 9 (above); Robert Zemeckis' version of Charles Dickens' A Christmas Carol, featuring Jim Carrey, Robin Wright, Colin Firth, and Michael J. Fox, among others; Ron Clements and John Musker's The Princess and the Frog, a fairy-tale set in Jazz Age New Orleans, and voiced by Oprah Winfrey, Terrence Howard, Anika Noni Rose, and others; and Adam Elliot's Sundance opener Mary and Max, about two unlikely pen pals, an 8-year-old girl (Toni Collette) in Melbourne and a 40-something man (Philip Seymour Hoffman) in New York City.

Also in the running are: Carlos Saldanha's Ice Age: Dawn of the Dinosaurs (above); Rob Letterman and Conrad Vernon's Monsters vs. Aliens; Aristomenis Tsirbas' Battle for Terra; Jorge Blanco's Planet 51; David Bowers' Astro Boy, with voices by Nicolas Cage, Charlize Theron, and others; Klay Hall's Tinker Bell and the Lost Treasure; Masayuki and Kazuya Tsurumaki's Evangerion; and possibly Stéphane Aubier and Vincent Patar's A Town Called Panic.


UP is just uncompetitive :)
I personally nominate "How to Train Your Dragon", "Toy Story 3" and "Up" for the best animations.
There are many other animations which I really like and would love to mention but those 3 are the ones that caught my eye the most …
'UP' will Win…
Up should win. Coraline was just a mediocre video game.
I believe you're right. I'll do a full update in early January, after all the critics' votes are in.
I believe The Princess & the Frog also has a good chance of nabbing an oscar. This has been a very good year for good animated films.
