In theory, dedicated servers for the next Halo title means that the host never leaves the game. Which means the film will always be reliable.

Which in turn, means if every game is hosted on dedicated servers.. it's technically possible for Microsoft to make the film of every game available from the server's perspective. Go to your game history on Halo Waypoint, click a game, and download the film to your Xbox to watch it.

Would you make use of such a feature? This is anyone's game history, by the way. Meaning I could go to say Wu's game history and download his latest Team Slayer game and watch it.
