Was always to be an exclusive for Microsoft platforms
and Respawn are now officially confirming that as of right now the first Titanfall game is a Microsoft platform exclusive. This means that the game will only be released for the Xbox One, Xbox 360, and Windows platforms. Because of this exclusive there are no plans to release either a PlayStation 3 or PlayStation 4 version of Titanfall.
Vince Zampella of Respawn claims that Titanfall was always to be a Microsoft exclusive title. It was a deal that was made by a new developer and was a deal that was best. Future titles in the Titanfall franchise could be released for other platforms, but the first title will continue to be a Microsoft platform exclusive.
