I just got to thinking about something I haven't seen discussed: "Will this game have cinematics?"
I imagine they could have a "You win, Good for you!" or "You failed, now Russia owns all of europe" clip, although that would be a bit cliche. (Remember the early C&C games that did that?)
There could also be cut scenes for the singleplayer segment leading up to world war III.
Then of course, there is this possibility: what if they had a fake news cast outlining events of the war (like they've done on the viral site)? They'd probably do it at key points durring each campaign and of course the end of each campaign.
