Quality content is still important if a company wants my money. I'm not sure if it needs to be exclusive content though. I do think a platform holder can differentiate in other areas (robust, easy to use online services, movies, TV, integration across multiple devices, etc). I don't know. My answer would have been different 5 years ago. Times are changing though. As I get older and have less free time to game, the convenience factor is even more appealing to me. Locking down content I want on to an exclusive device can be at odds with that convenience factor.
