Read this blog, especially the last two sections. *http://masseffect.wikia.com/wiki/User_blog:Kaloneous/Mass_Effect_3_(True)_Ending_DLC_Revealed%3F%3F%3F

Sorry guys, it doesn't look like BioWare is going to change the endings at all and will instead give dlc missions prior to the concluding part of the game.
