Warren Spector was asked about creating a trilogy. He said that was what he had in mind. These are some of Warren's exact words:
- "I don't do anything that isn't extensible. And I will certainly feel that I have not done my job if we can't make other games in this world with these characters. In my head, I've got two more planned."
Spector also said that just because someone plans a trilogy, doesn't mean it will happen in reality. Spector also confirmed that he had an "idea" for the story of Epic Mickey 3. Spector has stated that the musical bits of Epic Mickey 2: The Power of Two were a "test bed". Depending on the reception, for the next game he would have been going crazy with the musical songs, with Epic Mickey 3 possibly being a full blown musical. Depending on the timing, the game could have seen a potential release on the next generation's platforms.
On January 29th 2013, it was announced that Junction Point Studios was being closed by Disney. Disney, however, does still have the IP for Epic Mickey, but no plans have been announced to continue the series, meaning the chances of another entry are slim. As is the case with many cancelled games, petitions have been made by fans, though none have persuaded Disney to select a new developer.
On 30th April 2015, Warren Spector responded to questions regarding the game. He stated that he really wanted to up the multiplayer action and make a truly interactive musical game and make music in the context of a game that no music-game has done yet.  Warren also stated that the third game would have left Wasteland.
A brief teaser was shown at the end of Epic Mickey 2, showing all the Petes going to Vertureland with a fearful Gremlin Prescott trapped in Big Bad Pete's hand. Pete then says: "Look at them all, so happy. They ain't even going to know what hit 'em!" This showed the possibility of the Petes being the villains of Epic Mickey 3. If you also thin out various areas in the Mad Doctor's Attic in the sequel, you will find costumes that Gremlin Gus and Oswald aren't suited for. This hints that the Attic has become the hideout of the Pete's, since the area is connected to Ventureland and that is where the Pete's go after the events of the sequel.
