As we already know, the new Call Of Duty game, this one handled by Treyarch will be officially unveiled later today on GTTV. There’s plenty of rumour and speculation out there as to what the game will actually be called and where it will be set but we have it from Venture Beat via Kotaku that the new game will officially be called Call of Duty: Vietnam. There you have it. Nice and simple. We like it. Let’s just wait for Geoff Keighley and the guys over at GTTV to confirm it later on today.
