I'm willing to give the benefit of the doubt. Actually, I'm more waiting til I hear it from his own mouth, to make sure his quotes weren't taken out of context or mistranslated or anything before I'm gonna cast judgement.
See... 40 feels like overkill unless they absolutely, positively stepped on the gas in this respect.
Even 4 different endings, a la, say, Fallout New Vegas ( join NCR, join Legion, join House or prop yourself up) if they are the "culmination" of decisions (much like New Vegas where you see the narative branch off quite early depending on whose side you are on), that would be just great for me.
It's not the numbers that do it for me, but how each action is a brick in the ending you yourself are building (better yet, not even knowing action A will have consequences down the road); be that a good ending where things fall in neatly or bad ending where your selfish actions blow up in your face.
Come to think of it, for an open-world game, Fallout New Vegas allowed for a huge amount of narrative freedom, allowing the player to juggle with the regional politics in very diverse and satifying ways. It's been a while, but the epilogue to Fallout New Vegas felt very satifying.
It's just that... the last time Bioware pulled off that kind of "here's how all your actions affected the world" was back in Dragon Age : Origins. A good few years ago.
For all we know, the people now in charge are just fine with Dragon Age 2 / Mass Effect 3 "minimalistic" epilogues.
