"After a tech demo at Play.com Live presented by Patrick Redding, Game and Narrative Designer on the Ubisoft Montreal developed Far Cry 2, we asked Mr. Redding about plans for future downloadable content. Apparently, the infrastructure for future DLC is in place, and apparently some form of expansion is being planned. He also said that depending on the expansion, it might be released on another disc or via DLC methods on the consoles. However, he made clear that they're fully focused on getting the game done, and only have set structure in place to make things slightly easier when they get round to creating more content.
Redding also revealed that they're looking into Sixaxis motion technology, and are looking to their game testers to evaluate the viability of it. We actually asked him about DualShock 3 rumble support, but his answer was far more interesting than inclusion of force feedback."
