It appears that Titanfall 2 will be releasing most likely between late 2016 and early 2017.
Respawn Entertainment’s EVP Blake Jorgensen stated during EA’s investor call yesterday that,
“In terms of Titanfall, you should assume that that’s not in fiscal 2016. It’s more likely in fiscal 2017…. And a title of that size, we want to be pretty clear as to when it’s falling in the title slate, and so your assumption should be 2017.”
A couple of months ago, Titanfall 2 was revealed to be in the works when Respawn founder Vince Zampella stated, “So we’re working on a sequel. No official name yet, but we’re working on that.”
