As part of an earnings call today, Electronic Arts CFO Blake Jorgensen announced that Titanfall 2 is not going to be released anytime soon. Responding to an analyst's question, Jorgensen said you shouldn't expect to see Titanfall 2 until EA's fiscal year 2017.
That means Titanfall 2 is due to launch sometime between April 1, 2016 and March 31, 2017.
