Regardless of the price of either PS3 or 360, there just HAS to be a shift away from the traditional exclusives, and more multi-plats across the board. People just expect so much more .. bigger worlds, more realism, accurate physics and lighting, etc.. It just isnt enough to create a city of flat box houses anymore .. and that cost will be borned by the devs. Somehow this cost must be made up, and unless someone hands them a bucket of money to retain exclusive rights, it just doesn't make financial sense to create all of that art asset, and then limit themselves to one segment of the total userbase.
