One thing missing from the Disney Epic Mickey 2: The Power of Two reveal this last week was any mention on the rumored 3DS spin-off title, Disney Epic Mickey: Power of Illusion. Disney has still not confirmed the existence of the game, but that has not stopped Nintendo Power from previewing an exclusive article about it in their upcoming April issue.
Details on the game come only from the online preview of the article, and are therefore pretty much non-existent at this point. All we really know now is that Power of Illusion is not being developed by Junction Point (the developer of the console versions of Epic Mickey 2) but is instead coming from Dreamrift. The only other bit of information currently known is that the 3DS title is scheduled for Fall 2012, which means that it is most likely going to launch at the same time as Epic Mickey 2 on the Wii, PS3, and Xbox 360.
