In a recent podcast appearance, Dragon Age creative director revealed that Bioware isn't done with the series yet. Here is what he had to say:
"As I've jokingly said, I am the creative director for the Dragon Age franchise and they haven't fired me yet."
He went on to explicitly state that "something is happening with the series"
I gotta say, I certainly hope the future of Dragon Age isn't in the same hands that made Andromeda....
