My two cents... there has always been theatrical cuts and directors or extended cuts of movies. Even some authors make their own "definitive" edition, adding things and all around cleaning up the flow. Never been much of a bad thing in those mediums, and considering we don't have to buy a NEW COPY of the game to get this I feel the sit back and wait approach is best to see what is "extended" in this FREE DLC. Many movies have been made better by those Directors Cut versions.
How development goes nowaday anyway, and the fact that this still EA we are talking about breathing behind them for a release, it makes complete sense to me the ending was super rushed. They probably had to make compromises. They most likely tried to convey the ideas they wanted to with what they had available. They took a swing and missed, but its not the end of the damn world.
Ever create something, anything, be it short film, story, artwork, or music and other people do not see what you tried to convey? That is what I see with the ending of ME3. They were forced to convey a large amount in a short rush of end development, and we don't see what they were trying to say.
Not going to hold my breath for something epic in this Extended Ending DLC, but making it not horrible is a start. I think Bioware could take a big lesson from the Silent Hill dev teams about how to make differing endings that actually mean something
