According to its blog, Capcom encountered “An unforeseen error with the Valve submission process has caused a delay on Steam, preventing a timely release of the DLC on that service.” which means no new content for the majority of users.
However if you use Games for Windows LIVE instead, you’re in luck, because the DLC is already uploaded and ready for use, which is kind of ironic when you think about it.
