Disney has announced today the continued development of Disney Infinity 3.0 without the release of a sequel later on this year. It will  come to no surprise as Disney will instead release a number of new play sets and characters to keep your interest in Disney Infinity until then.
We could maybe be seeing some of Disney new movies such as Zootopia, The Jungle Book, Captain America: Civil War, Alice Through the Looking Glass, Finding Dory, Doctor Strange, Moana, and Rogue One: A Star Wars Story joining the long character list. Marvel Battlegrounds will be the first new play set coming to Disney Infinity 3.0 on March 15th.
