Titanfall originally released on the Xbox One, Xbox 360 and the PC, making it an exclusive for Microsoft platforms. Whilst it wasn't confirmed, at the time of the release, many were assuming that Titanfall would lose it's exclusivity by the time the second title was released.
Let's be honest, Titanfall 2 probably is coming, and Respawn Entertainment are going to do all they can to keep it from dying out before the franchise has even had a chance to flourish. One way for Respawn to accomplish this is to reach out for a multi-platform release, including the PlayStation 4.
So far, nobody at Respawn has confirmed in words that Titanfall 2 will be on PS4, but a new comment by EA CFO Blake Jorgensen kind of suggests that it won't just be the Xbox that will be getting the Respawn treatment in the new future.
Jorgensen stated - "Last year it was on the Xbox only; in the future, we haven't yet announced, but we'll probably have another Titanfall game. It will probably be a bigger footprint than just a single platform. I think that's a huge positive for us."
If there is a more obvious way of saying Titanfall 2 would be coming to PlayStation 4 without actually saying it, I'd be excited to hear, because as far as we're concerned it looks very likely that a Titanfall sequel will be coming to multiple platforms instead of just the Xbox One and PC.
