I can't see this happening for a few reasons: 1) Titanfall was hamstrung by the X1 install base and only sold 2.5M units, By the time of release (2016?), there's a very real chance there will be 40-50M PS4s and 20-30X1s sold, and 3) Destiny sold almost 2X copies on PS4 as X1 (4.6M vs. 2.5M), which would have required MS to pay Bungie ~120MM to offset lost sales (with a much smaller install base).
It's possible, just seems very unlikely that both parties would be willing to bite that bullet.
