"While we will still be keeping an eye out for any issues that might crop up in DAII and supporting the community should any emergencies should [sic] arise, we're moving the entire team's focus to the next phase of Dragon Age's future," Darrah wrote.
The "next phase of Dragon Age's future" could be too vague for some, so creative director Mike Laidlaw clarified in a TL;DR Twitter update: "We're done development on Dragon Age II, and the team has fully moved onto The Next Thing(tm)."
BioWare halted production on Exalted March, an expansion pack for Dragon Age 2, because "other Dragon Age opportunities came up," Darrah tweeted. It's safe to reason that stopping production on DLC probably wouldn't happen for anything less than work on a shiny new title, and with these scraps of evidence and previous unintentional outings, we feel safe to propose that BioWare is now working on Dragon Age 3.
Moving the franchise into the future involves looking at the past, Darrah said. "This past year, we've spent a lot of time both going back to the 'BioWare vault' of games and re-examining them, and looking at some new possibilities that today's industry allows," he wrote. The Dragon Age team may not have to look very far in BioWare's history to find things it should avoid, such as "endings."
