User blog comment:Kaloneous/Mass Effect 3 Ending DLC Denied and PAX/@comment-4043223-20120405160210

Here is the iofficial statement.
 * Link.

Also, the ME twitter feed has confirmed that since the Mass Relays are destroyed and the endings are not going to be changed then this is canon and in line with their artistic vision. (I am looking for the link and will post when I find it but as you'd expec t the twitter feed is manic at the moment).

Also, regardless the BSN forums are on fire as the epilogue scenes will (supposedly) focus arounfd the crashed Normandy and life as it developed from that eden planet.
