Nobuo Uematsu is the current favorite in the Composer Pool.
Anyone care to place a bet?
Matoi Sakuraba would be my pick based on his wide musical range (he can certainly pull off a Final Fantasy-style sound given his Baten Kaitos, Eternal Sonata, and Valkyrie Profile soundtracks), though Uematsu is always a popular pick. Personally, I hope it's not Uematsu because I feel like he lost his composer's touch around FF IX (X's soundtrack was only as awesome as it was because he had two other composers working with him).
The JRPG genre needs what Batman: Arkham Asylum did to the Stealth Genre. A killer app that inject new life into a genre on the decline.
Well, we've had several games now that are surely trying, the most notable of which recently have been FF XIII (with its focus on continual action and high-risk, high-reward strategy in large set piece moments) and Resonance of Fate (with its gun-heavy battles and a sand-box approach to world and character building). I thought Valkyria Chronicles made an excellent stab at redefining the Strategy RPG (though, sadly, I don't think it sold well enough worldwide to have such an impact) with 3rd person shooter mechanics and a novel style. Then you have the Persona games (3-4) with their melding of the dating sim/Japanese pop culture/dungeon crawler in a modern setting. If Atlus has anything to say about it, the next big thing in RPGs will probably be the contemporary setting (a contemporary take on Final Fantasy could be interesting, incidentally) with an emphasis on action and steady pacing.
As for the story itself, I'm really getting sick of Sakaguchi hyping this game with nothing to show for it. He can toss out all the concept art he wants, but until he can back it up with
actual in-game screenshots and videos, I'm calling BS on the entire game.
