A French Nintendo magazine is claiming that Epic Mickey 2 is going to get a companion game on the 3DS. The magazine sent out this Tweet, which has been Google translated.

“The presentation of Epic Mickey 2 will take place next week. 3DS version, Power of Illusion, more “classic” 2D is also planned.”

A companion game in 2D on the 3DS sounds like a great idea to me. Let's keep our fingers crossed for a confirmation!
