Tomb Raider as a MS exclusive makes a fair amount of sense even though it is leaving money on the table for the larger audience on the PS4.
Considering that the PS4 has Uncharted and would rather have PS4 owners buying that game rather than Tomb Raider, it also makes a fair amount of sense why they would let it go; there's very little to be gained other than a potential title that runs better on the PS4 than it does on the XBO.
I remember that the TR franchise was exclusive to the XB360 for the first couple years. It wasn't until the release of TR Underworld that the franchise finally showed up on the PS3. I remember because TR was one of the franchises I bought an XB360 for before the original Uncharted made me lose my taste for it when I realized how dated it had become.
Why Capcom agree to make Street Fighter a PS4 console exclusive (let's just say leave it off the XBO) is a mystery to me though. Money incentives from Sony obviously, but it's not like Sony is bankrolling Street Fighter V; I seriously doubt it's a huge compensation check.
But then again, like everyone is saying, there's nothing to stop Capcom from selling SF V: Annual Update #1 on the XBO unless that was a part of the deal, which would make even less sense.
(EDIT)
Wow. I had no idea Capcom was in such financial dire straits; they do need whatever Sony is paying them and it also explains why SF V is essentially using an updated version of the SF IV game engine. Capcom doesn't have the R&D budget to completely revamp the game.
