Along with some of the exclusive DLC's, there is apparently one free DLC everyone will get:

"Each new copy of the game will come with a one-time-use code that will unlock new multiplayer maps (Codestream Nexus and User's Plaza) along with a Sam Flynn multiplayer skin. With the free content included, this brings the total number of multiplayer maps to six; Disney is promising that more maps will be available for download in the coming months."
