Sounds like they are really trying to overhaul the game, and that's exactly what this franchise needs.
"The multiplayer is being entirely revamped as an all new experience, with staples like killstreaks and create-a-class seeing complete overhauls. Treyarch is paying a lot of attention to the professional gaming community to ensure that the new modes are competitive on a much deeper level."
Pretty exciting stuff! Treyarch is approximately 1 million times more creative than Infinity Ward. So, I think we will have a Great game here! Just one aliens opinion!
They're all good innovations on the CoD formula imo, though considering the money these games generate and how much they avoided spending just recycling so many assets with each game it's about time they did something more ambitious.
