"We have a very different approach to exclusives than some of our competitors," stated Tretton. "We don't buy exclusivity, we don't fund development. We don't, for lack of a better term, bribe somebody to only do a game on our platform."
"We earn it by saying, 'You can build a better game on our platform. If you focus your development on our platform, you will ultimately be more successful. We can try to partner up with you from a technology standpoint. We can try to partner up with you from a marketing standpoint. But just economically and technologically, this is the system that makes the most sense for you.'"
"There are a lot of great developers out there, and they always figure it out," Tretton stated.

Sony I love you your ideals are always intact and true.
They may be intact and true but exclusives are going to all out of the sky in Sony's lap like they did in the past they really have to fight for them now since MS is eating them up.
