I heard some terrible things about it's loading times...

I think Sacaguchi made a bad decision when he decided to focus more on story and keep the old FF gameplay.
RPG fans in the west want new things and innovation in their games and this is anything but that.It's an exclusive to 360 so therefore i think in terms of sales this game is doomed in the west.
Of course he mostly tried to lure the Japanese gamers but the problem is 360 keeps on failing to attract the japanese yen...
