Although it's not ready to talk about it, the Extended Cut DLC definitely isn't the last extra content BioWare has planned for Mass Effect 3.
"Would now be a good time to talk about how we're doing more DLC in the future?," BioWare's Mike Gamble joked on Twitter.
"That was a trick question. We'll save the future DLC for future chats. Don't worry though. There's much more," he added.
BioWare has said in the past that it plans single-player DLC based on what players want; the Extended Cut, while not adding significantly to playable content directly addressed fan complaints over the game's ending. The only significant single player DLC to release so far was the From Ashes pack bundled with special editions, although several multiplayer updates have been released.
