ME3: New Endings?

Is it possible that BioWare and E.A are fibbing about the Endings? That they could be releasing something in the future, new Ending Stories and Gameplay. I know about the Extended Cut whatever that is. I know people been saying there aren't new Endings, I don't care about explanations. I know that I suck at explaining. I hope that we do get better Endings. I also hope we get other New variety of Contents as well.
