What do you think about the Mass Effect 3 ending? Do you think Bio will actually release a better dlc ending like requested? I myself have a feeling there mite be a mass effect 4 coming.

I don't know about a Mass Effect 4, but they have promised extra content initiatives for the ending. While I personally didn't hate the ending, I still thought that they definitely could have improved it, and that is what they seem to be doing with this extra upcoming content.

I'm just going to comment on the "Mass Effect 4 question" by saying if you played through ME3 and watched till the end of the credits there was a clip opening it up to countless more installments. I don't think they will pick up Commander Shepards story anymore but they have stated that the ME universe is big enough to tell many many stories. So in my opinion there will be future ME games but not involving the same story line.
