Appears to me like the game was already certain to be on the Xbox which at this point it was most likely the lead platform.
Microsoft was talking with them about Durango very early on and courting them to move Titanfall over to that.
Sony were imo just being careful in dealing with E.A, Respawn a new IP and they maybe knew about MS getting involved early. It's understandable that Sony would be careful in this instance. They were willing to thrown them a bone by offering up the Vita. In the end the game was a good one, you win some you lose some. No big deal really.
