G4 has uploaded a quick 47-second clip of actor Lance Henriksen (Admiral Hackett) talking about the recording session BioWare recently tapped him for so that they can revise Mass Effect 3's controversial ending in future DLC. He calls the "abrupt" ending "an oversight" before claiming that the team has done "a whole series of things" to flesh it out further.
Hopefully these additions won't cost us any money, but I'm definitely not going to hold my breath.
