This. The last Final Fantasy that interested me was 10, and (prepares for angry reaction) I felt really let down by that. Nothing since has really impressed me.
But the concept for this looks good (albeit yes, AK-wielding "terrorists," but it's definitely different from standard FF fare as far as I can tell), and DAMN - those graphics. Now, if they can just deliver a fresh story, I might actually buy it. But I'll wait and see.
