Respawn founder Vince Zampella is working on a free-to-play version of Titanfall on PC with Nexon, as well as a mobile version of the game, but he also dropped hints on the sequel, Titanfall 2, today.
While Electronic Arts has stated that Titanfall 2 won't be ready til 2016 or 2017, Zampella stated in an interview regarding the sequel, "I can't say just yet, I promise that it will be worth the wait."
Titanfall 2 will be a simultaneous console and PC release when it does finally get launched.
