As I've stated a few times before in comments even though I'm a none Mass Effect player I understood the fan outrage over how the endings were in pre extended cut, it didn't explain worth of anything and all the endings felt the same no matter what you chose. In the extended cut endings 2 endings dictate Shepard dies like in pre extended cut but shows Shepards love interest put his name on a Memorial as if he died.
However even in the Original Destroy Ending if certain conditions where met you would see a cutscene showing Shepard gasping for air underneath rubble, in the extended cut Destroy Ending who ever is Shepards Love Interest in the players story she hesitates to place Shepards name on a Memorial having faith Shepard is alive somewhere. Bioware on their forums has confirmed this to be the case with this post
Could Bioware have stated that the Destroy Ending in Mass Effect 3 be the Cannon Ending to the series? If so does this mean more Mass Effect is apun us? Only time will tell. For those that havn't seen it, the Destroy Ending Extended Cut is viewable down below
