I can't believe I'm actually excited over a new CoD game, but...
I like the direction CoD is going this time. They're going into the future. Not like Blops2 near-future BS, but for realz brah. 2054(!) according to the article.
Also mentioned in this summary of the article is how you can upgrade your EXO suit (which the player gets in sp). This means that they're going back towards SP cuztomizability/leveling up, which I liked about Blops2.
Lastly, the protagonist now has a voice again, and he's played by none other than Troy Baker, who played Joel from The Last of Us and Booker from Bioshock Infinite.
