Sorry had to edit your title there, there was nothing saying there will be a new ending:

The game's controversial ending was also a popular subject on Reddit. Fans were given no definitive word as to how it should be interpreted, but Druckmann promised he and Straley will share details on some of the proposed alternative endings during a panel at this year's PAX Prime.
This meaning they either might be planning on releasing one or they will just be discussing some of the other ideas they had.
Still I really am looking forward to the singleplayer DLC. I have no interest in the multiplayer but I am hoping the new singleplayer stuff does extend the ending some.
