If they go through with naming it Call of Duty: WWII, it will be kind of hilarious. It's like they are conveniently forgetting that the first three or four games already took place there, and this is some brand new direction for the series.
Are we sure it dosent mean World at War 2? And that WW2 is just a you know, play on that?
I thought of that as well, but I think Treyarch would be rightfully pissed, and Activision would be quite dumb to piss off their best COD studio. Black Ops 3 > Infinite Warfare / Ghosts > Advanced Warfare.
Then again, maybe Treyarch is exploring truly original territory for the series, and they'd be fine to let another studio make World at War 2. I guess we'll find out eventually.
