"...read on for IGN's exclusive first interview with Todd Howard, Game Director for Fallout 3, that dives into more details on the newly announced add-ons as well as extra details on the port to PS3.
IGN: Was the eventual PlayStation 3 release for the existing DLC always in the works, or was it something that came up after the fact?
Todd Howard: We always wanted to do it, but until it actually looks like it will happen, we don't want to make promises. We've been working on it and they aren't done yet so it's going to take time for each DLC to be moved over to the PS3 and work well. As a result there will still be a month or so gap between each one once they start hitting on the PS3."
