Considering selling the players a new ending as DLC, mark my words.
People are pissed at the ending for many legitimate reasons but I don't think it should be redone. Vent your rage in the form of not buying future Bioware products, this bullshit about getting them to "change" the ending is just silly.
They promised one thing (literally) and failed to deliver, hit them where it hurts.
It might not be the best ending I've ever seen but there's nothing intrinsically wrong with it
It goes against everything that the ME series was all about (player choice, multiple paths, etc) so I'd say there is a lot wrong with it in the context of it being an ending to this trilogy.
