This is a good point, at least people would act differently. Personally, I don't think I'd be all that interested.
Such is the power of brands - we've come to expect Awesome Things out of the Final Fantasy brand, which has two effects: it puts people's expectations into the stratosphere (which can be bad if they don't live up to those expectations) and it makes people interested in the game when it wouldn't have necessariy caught their eye as some random RPG.
The thing is, the two people who really really made FF shine, have gone. They're busy making things like Lost Odyssey shine. And so far, their successors have yet to prove that they can do much without essentially rehashing old material (X-2, XIII, vsXIII etc) or abandoning most of what people expect and doing practically a different concept altogether (XII). The brand name is still there, most of the people are still there, but the soul has moved on.
(I hope to be proven wrong)
