Next Mass Effect Due Sometime In 2014-15
Though it's honestly hard to say, since work only began recently.
UPDATE: We have written a follow-up to this story here.
We all know that another Mass Effect game is on the way, so the real question is when it'll be arriving. And as it turns out, we already have an answer, generally speaking.
In an interview with Gamer Syndrome, producer Mike Gamble was asked to provide a rough idea as it pertains to a possible release window. Surprisingly, one was offered:
"Late 2014 to Mid 2015. I honestly can’t tell you an exact because full development on the game started a month or two ago."
Also, when asked about the changes in both the studio and game engines:
"While I can’t comment on why it changed studios, fans can expect a similar style of choices and action that they’ve come to know in Mass Effect. Casey Hudson is very much involved in the new Mass Effect game, as well as many from Edmonton. BioWare Montreal is a great studio and they did fantastic with the multiplayer for Mass Effect 3, so fans should know the series is in good hands.
The game isn’t far along in development so I can’t comment on specifics because they isn’t any yet, Frostbite 2 is a really good game engine that we are also using on Dragon Age 3."
And finally, while no platforms have been announced, a Wii U version seems all but certain.
"Wii U is a console we feel is really cool and that more Mass Effect would look great on it, so we do have plans for Wii U but nothing to announce at this moment."
