The only reason Sony got franchises like Final Fantasy, MGS, Tekken, etc. exclusive in the first place was because at the time those games were impossible on the N64 (because of cartridge-only) and the Sega Saturn was a train wreck and a commercial failure.
Sony was the only option. The PS2 won the last generation before the GameCube and XBox even came out. So again they retained their hold on third parties. That is not the case anymore.
Those third parties don't owe Sony anything. Sony benefitted tremendously for years. If Nintendo and Sega had the same third party support as Sony did back in the day, it's very likely Sony would not have come close to dominating in the past, the situation then would've been more like it is today with Sony in a dog fight.
