From The Unofficial DisneyWiki

Oswald the Lucky Rabbit was a character made by Walt Disney and Universal Studios. Universal took control of Oswald but Disney eventually got him back in 2006. They will be unveiling Oswald as a meet and greet character in the parks sometime.

Oswald will also be playing an antagonistic role in the upcoming Wii game, Epic Mickey. In the game, he will be ruler of of forgotten Disney rides and older characters. Oswald becomes jealous of Mickey's fame, so he unleashes the Phantom Blot on the Disney universe, causing everything to be covered in ink and fading its colors.
