If anything, I think the Wii will become more dominant next year. This year was sort of the "trial period" for the console - and in general, it has passed with flying colours.
We'll see though - to date (IMO), all of the PS3 "big hits" have failed to capture the market (Gundam, Dynasty Warriors, HotShotGolf) - WKS, MGS, etc.
I don't think FF will come into the equation until 2009.
For the PS3 to truly succeed, it needs to demonstrates true "next-gen" titles that just aren't possible at the moment. The Wii has been the only console (this year) that has been introducing "true" new gaming experiences. The PS3 needs to move away from prettier versions of old games, into new gameplay experiences.
(I'm guessing GTA4 is going to be a great example of a real next-gen title...)
