While EA has not yet officially revealed a specific release date for the next Mass Effect, Titanfall, or Battlefield, it has narrowed down their release windows. EA had previously stated that Titanfall 2 (or whatever it ends up being called),
the new Battlefield, and Mass Effect Andromeda would be out during fiscal year 2017, which runs from April 1, 2016 through March 31, 2017. Not that there was any reason to believe they would be out prior to this fall, but CFO Blake Jorgensen confirmed during a conference call with investors today that they're all slated for launch during the second half of the fiscal year. That translates to sometime between October 2016 and March 2017.
"You should assume that a Battlefield will come typically in the third quarter, when we normally have it," he said. "We're not yet announcing when Titanfall or Mass Effect Andromeda will come, but you should assume that's in the back half of the year as well because the second quarter [July-September] is so dominated by our sports titles."
We, however, don't know much about the three games.
