Polygon: Tomb Raider's Xbox exclusivity likely means more sales, higher profits

[starcraft]

"It's very possible that the game's existence itself is due to this exclusivity deal; without Microsoft easing the cost of the game's development and supporting it upon release,Rise of the Tomb Raider may have never been given the green light to go into full production."

Entirely speculation, but that would debunk a lot of the whining from the last couple of days.
