Well IGN's Colin Campbell (Head of News and Features) confirmed that any closure dlc will cost extra during an interview with (shudders) Colin Morierty. link here: http://ie.ign.com/videos/2012/03/21/mass-effect-3-a-dangerous-precedent

Also, Gamerlive.tv Interviewing the one and only Mark Meer, confirms that he has been asked to reschedule a dialogue type sequence (narrator) for a new dlc part. My take on this (and this is my guess, I have no facts only my theory) is that they will do a cutscene with a voice over of Shepard.... we'll have to wait and see in April though.
