new pricing models for outsourcing agreements

I have seen this a couple of times lately, most recently in a Whitepaper on Outsourcing 2.0 from the Outsourcing Institute, that outsourcing vendors and clients need to work out new pricing models. Something that the industry has not seen yet, something to better serve the industry. I have thought about this as well, and I am curious to ask if anyone else has seen what they consider to be "new pricing models" for outsourcing deals?
