Fans can also expect "Star Wars" attractions at Disney theme parks.
"They are coming," Iger said.
"There is work being done now … to develop those properties and I say properties plural because it will be at more than one theme park."
He wouldn't divulge any further details.

Meanwhile, teams are hard at work producing merchandise to tie into the film. The franchise has been one of the most successful ones ever and is still quite popular, Iger said.
"This is likely to be one of if not our most valuable property once the movie comes out."
Disney paid $4 billion for Lucas Films in October 2012, which Iger called a positive move for all involved.
"We already are fairly confident that it was a good deal for us and it's been a good deal for George Lucas as well because he took cash and Disney stock and the Disney stock has appreciated significantly since less than three years ago when the acquisition was made."
The company is planning six movies in total—"Star Wars" six, seven and eight as well as three stand-alone films, or spinoffs.
