BioWare Talks Mass Effect 3: Extended Cut DLC

The Penny Arcade Report has a feature on a PAX East Mass Effect 3 panel where apparently, among other things, the upcoming Mass Effect 3: Extended Cut free DLC, made to provide "clarity" and "closure" to the title's negatively received ending, was discussed. Apparently the company's goal is to provide some sense of "personalization" to the ending:
So what's the point of the content? (We want to give more closure about some of the questions you have,) Gamble explained, (and in general we wanted to give the players a sense of personalization with the endings. Many people mentioned that some of the choices they made in the game are not necessarily reflected in the ending scenes. We're definitely going to focus on things like that. We want to make sure that when you see the ending of Mass Effect, you now have the information and context to be satisfied.) They're shooting for a (generic summer) release, and we're told to expect a decent amount of content; the new information won't be rushed. (It's more than just a few cinematic scenes,) Gamble said. (We're happy to be doing it.)
