Tomb Raider franchise recently resurrected, after a long decline, but with far better sales on PS3 and PS4 than on XB360 and XBOne, so giving up completely a PS4 port would be a short-sighted gamble, selling MS a timed exclusive for as much money as possible makes a lot more sense. Also, interrupting the saga with a missing episode on the leading platform could damage sales of successive episodes on it.
