Confirming the project's existence, Disney are set to unveil their Disney Infinity "gaming initiative" on January 13th 2013, according to an event invitation sent to Polygon. Not much is known about Disney Infinity, but rumours suggest that it is an ambitious Pokemon-esque project intended to span multiple platforms, online services and mobile devices with a big emphasis on physical merchandising of Disney characters (via Polygon):

While the invitation doesn't detail what exactly Disney Infinity is, Disney fansite Stitch Kingdom reported last month that the project was initially codenamed Toy Box.

Disney Infinity is an ambitious project from the studio which will use collectible toys with embedded NFC/RFID chips to interact with console games, according to that report. The game, which sounds similar to Activision's Skylanders, will be bolstered by Disney and Pixar's characters and run on several platforms including console, mobile and computer.

In an article about an interview with Pleasants in October, the New York Times described Toy Box as a "console game with extensive mobile and online applications in which various Pixar and Disney characters will interact with one another for the first time."

The event is said to feature both Pixar's John Lasseter, and Disney Interactive's John Pleasants, perhaps validating the rumours.
