I want to see more on the film/recording thingy. If that is a fully developed feature and players can go back and look at every kill and record those and share them easily on youtube or facebook, or there is some sort of live specific service, they this game is going to go fucking crazy.
Remember that crazy knife kill that went viral? Guy throws knife over a building ends up killing a player, last kill of the game, gets replayed to everyone in the match. That shit is going to keep people playing this game. I'm hoping they saw that and a light went off in their head and they made getting those video's a key part of the MP game.
Add in all that customization and you can quickly get thousands of awesome video clips that will catch the attention of anyone with a pulse and a set of balls.
But if they didn't, and it's just some stupid gimmick attached to a camera that you have to manually setup and you are the only one who gets to see it...well then I think that would confirm everyone's worst fears about Treyarch being a bunch of hacks that don't bring anything substantial to the table...
Implementing that video feature well could take this franchise into 10x as many homes as it's ever been in. Fingers Crossed.
