Square Enix was not particularly camera shy when it came to cam grabbed Final Fantasy XIII-2 videos at E3, but Gamespot managed to get lots and lots of direct feed footage. Have a look here:
Live Trigger and Atlas Fight
Track Down Atlas
Paradox Alpha Fight
This one has a Square Enix rep detailing the game.
