"Disney Infinity launched one year ago, and in that time the number of Wii U players has significantly expanded," Vice President and General Manager of developer Avalanche Software John Blackburn said in a press release. "Given our commitment to compatibility for our players, we wanted existing Wii owners to be able to experience the Wii U version of the first game for free. With the upcoming launch of the 2.0 Edition of Disney Infinity we want all Nintendo players to experience the game's Wii U functionality."
Disney Infinity 2.0 will release on Xbox One, Xbox 360, PlayStation 4, PlayStation 3, PS Vita, Wii U, and iOS on September 24. So almost everything you can play games on but the Wii. Offering Disney Infinity fans the game for free on Wii U seems like a good incentive to get them to buy Nintendo's latest console, and then hopefully Disney Infinity 2.0 and its future Play Sets.
It's also a good way for Disney Infinity to keep up with its main competitor in the toys-to-life category, Skylanders. In late July, publisher Activision announced a similar deal which gave owners of Skylanders Trap Team for Wii a free upgrade to the Wii U version.
