None of the items on your "very pssible" list have a good chance of being there. Those are mostly really big games, and rarely if ever do publishers release new trailers for massive games at TGS. FF7 will be at PSX and DQXI will have its own press conference.
But, i do believe that Japan Studio will unveil its new game at TGS. Very possible it's Wild ARMs. The director already confirmed a couple of years ago that he's working on a new WAs project (or smth of that sort).
Hype.
