Here's the dates Gametrailers has for them:
Exclusive Gameplay Cinematic Trailer
Jul 28, 2010
Battle Report: Episode 11
Sep 2, 2010
But then again, gametrailers usually gets videos before they're put up elsewhere.
On a side note, I have to say the game is looking good. I just hope we can turn off the "Morale Bar" and have the traditional flashing flags as a judge on whether or not a unit is about to route.
