The geeks have whined, bitched, and moaned. Now they get to see the fruits of their labor. EA and Bioware are releasing free DLC that will expand (read: not change) the ending to the epic that is Mass Effect 3. The DLC will add extra cinematic scenes as an epilogue to the game. BioWare believes that this will strike a nice balance between between answering the fans questions and maintaining the artistic vision of Casey Hudson and his team.
Look forward to downloading the DLC on all three platforms (PC, 360, and PS3) some time this summer. And while they have it marked as expiring on 04/12/2014 they do plan on keeping it free and availble as long as they can, but they add expiration dates to all free content.
