I don't think it will. The exclusivity line requires at least a 50 million unit lead over its competitor. This is never going to happen. Whichever console wins the HD wars, it won't be by more than 10 million units, so neither will ever justify third party exclusivity without moneyhatting.
Hypothetically, 100 million sold, with fewer than 50 million PS3s on the market is what I think would be the exclusivity line.
