Well, from who's point-of-view?
Sony: Yes. They know there are enough people who will gobble up anything with the words "Final Fantasy" (and without certain toxic words like "Crystal Chronicles") in the title. And to play it, they'll need to buy Move, leading to increased sales for it. And more Move sales means a higher chance of getting other projects to support it.
S-E: No. They know that some people already see it as a spinoff for merely having the word "Versus" in the title. They will want every reason they can to get as many people to buy this. Given that some of the PS3 fanbase is against motion, to require an extra device will alienate those people, AND as a by-product, raise the price of your game without seeing any extra revenue from the increased consumer cost.
FF Fans: Maybe. It would depend on how it was implemented. If it's token waggle, like many Wii games, then it will be bad. If it reinvigorates the series, though, then it will be a win for almost everyone.
People expecting a Wii port: Out of their mind. Going back to at least FF6, the Final Fantasy name has been one about pushing graphics on its system. Since the PS3 is more powerful than the Wii, they will not do a "downport" (in their eyes) of any FF game. Even though they could have it looking good, it would still have either a slightly noticable downgrade in video quality, or it'd look less realistic, as S-E would go toward cell shading, something the Wii excels at. But it just won't happen.
