I don't think they've made a decision yet at all, but are just taking a "wait and see" approach.
If FFXIII comes out and sells like 4:1 on the PS3 (not saying this will happen) and the PS3 Userbase is booming (compared to the 360) then I think it will stay Exclusive.
If the PS3 version outsells the 360 version 1.5:1 and the userbases are still close in EU/NA, then it probably would go Multi.
But since this is all 2+ years away, a lot can happen.
i predict 8-9 million for ps3 or near to it lifetime.
and possibly 2 million on 360 lifetime.
RE: ff13 versus, may go multiplat. it really does seem now that analysts were right ages ago in that huge 3rd party exclusives will be a thing of the past.
the only games that will indefinatly remeain exclusive are 1st party games owned and funded by thier respected companies, or games like gears series or resistance series for example that arnt 1st party.... but are 3rd partys heavily funded and supported to develop specifcly on thier platform.
...not much time to post on here anymore, used to be some good ol times on VGchartz...
