Titanfall? The first one? Hopefully this is talking about Titanfall 2 instead of Titanfall 1.
Really, if Titanfall is going to stay exclusive to Xbox for a year, there is no real reason to bring it to Playstation after that. It's an online-only multi-player game. When Titanfall 2 comes out, no one will be interested in the original. It's a much different situation than single-player games.
The people interested should instead hope that Titanfall 2 releases on Playstation and that the developers learned a lot from the first one so that the sequel is a better game.
Personally, I don't think I'm interested; if I were, I'd just buy it on PC.
