Speaking in an interview, Saints Row 3 Producer James Torbit confirmed that there was plans for content similar to Red Faction's Battlegrounds spin-off and the Sy-fy Movie, but he couldn't say what they were.
"I can say that there will be, I cannot say what it is specifically. But yes, there's a big push for stuff like that, it's more than we've ever done before I think, and that will continue on into the Downloadable Content."
"We did (DLC) on Saints Row 2, we're going to do it more with Saints Row 3."
Saints Row: The Third is due out on PC, PS3 and Xbox 360 next year, and you can read the rest of our interview here.
