If you had the hope that a PS4 version of Titanfall may come someday like I did, you were sadly mistaken.
IGN reported today on EA's quarterly earnings call where CFO Blake Jorgensen stated Titanfall "is exclusive only for the lifetime of the title on Xbox One, Xbox 360, and PC." Remember, a similar exclusivity at launch deal was acquired for the first Mass Effect which later surfaced for the PS3 much later. Vince Zampella later commented on Twitter that Titanfall was "Always MS exclusive at launch," and that "EA made a deal for the rest."
I wouldn't hold my breath for a PS4 version anytime soon so if you want to play Titanfall, I'd recommend picking up an Xbox One or a dominant PC rig before Titanfall's March 11th release.
