It was confirmed last night that the Xbox 360 version of Titanfall would be delayed slightly, with the release pushed back to March 25.
The proposed March 11 launch of the other two platforms in question - PC and Xbox One - remains the same. The extended release date is so Bluepoint Games (who are handling this version of Respawn's shooter) can spend some extra time applying "the finishing touches". Xbox 360 fans - that two week wait is going to be agonising and we feel for you, we really do.
