The trailer is kind of funny in a way to me because I've been saying for years that cyber-warfare is the area the U.S. needs to focus on the most (defensively mostly) because that is what other big nations are working on the most since they can't match up toe to toe with them. The idea is to completely shut down the networks, take over unmanned vehicles, and cause general mayhem all the while gaining crucial secrets. Leon Panetta surprised me when he said that was the area he was worried about the most and that's where he'd like to catch up so at least they're addressing those concerns.
It's just different for a change to hear the story involve that (if that's what the trailer truly meant) as it's very different and hasn't really been touched on too much and it's the only real thing (besides the obvious nuclear warfare) that could be believable right now instead of the bullshit MW storyline as if an invasion is that simple. So we went from Red Dawn to a Clancy book that sort of makes sense, but there's a lot we don't know yet so I hope the rest is good. The fact that the storyline can change in some instances if you fail a mission is unreal for a COD game since a linear Michael Bay game has always been the approach. If the core gameplay is good and feels different, then the COD fatigue might wear off. I like their ideas so far.
Well played Treyarch for taking risks and trying to do something different. Here's to hoping that the PC version doesn't run like shit or any version for that matter and that dedicated servers will be back. I have full faith that they will be since they tend to listen more to the community than IW.
