Yes, yes... I know. And yes, I can feel the earth shaking force of palms slapping foreheads, but hear me out...
Just where do you think this game is going to end up? Let's hear some opinions on this. As for me, thinking logically about it, I could come to but one conclusion:
As a life-long fan of the franchise and a long time follower (since 1997) of everything Square has had their fingers into, I'm of mind to believe I share an opinion that the majority has held in it's heart (lolol). The most logical path going foward is to make sure the game is the most graphically (in terms of cool style and scope of the worlds) compelling experience Nomura's team are capable of achieving, this is why it'll most likely be exclusive... Or atleast until the next generation rolls around, then it can be ported... maybe.
This is where the power of the cell comes into play. Nothing will give me more pleasure than to see Sora's chains moves realisticly in realtime, 1080p, 60fps all while looking like the greatest Pixar movie you'll ever see, all thanks to the physics they'll be able to pull off on the smallest of details without even scratching the surface of what the cell is capable of. It blows my mind just thinking about it. In the end I imagine it'll look something like this:
ACTUAL GAMEPLAY FOOTAGE!!!
Well that's the main reason I think it SHOULD go to the PS3. They'll probably optimize the engine used for vXIII to get the results they need without bankrupting them. By the time it comes out though Sony would've sold around 80 millions consoles so there's no worrying about making the money back. In the meantime, the DS and PSP will continue to get spinoffs to help fund such a large project, maybe even the Wii will get one.
