It's difficult to expect how it will turn out considering this is a different Infinity Ward, and if you notice at the end of the trailer, Sledgehammer Games has its logo there too. (I believe Sledgehammer is some people who were formally at Visceral Games, or EA Redwood, or something.)
The same rumor also suggested the call of duty points are in single player as well, and there is a three player co-op mode.
I'll post the blurb if I can find it again. here:
We have just received from an unlikely source – but very trustworthy source – of some big Modern Warfare 3 multiplayer details. Although unwilling to give further details, what with the official gameplay trailer tonight, our source said that further details of it will be unveiled ‘in the coming weeks’.
Our source did say that the game will feature cod points, but in a heavily ‘redesigned and refocused way’. This could mean you earn it differently, as he said that ‘wager matches are unlikely to return’. It could also mean you spend it in different ways, as he goes on to say ‘single player has a very multiplayer feel to it, with some interesting ideas to it’. We can only speculate that this may be the ability to buy weapons in single player with cod points, although our source said not to take his word for that specific point.
He also said that there will be ‘a huge improvement in the number of maps, modes and game types’, and to expect ‘more people on maps than you would normally expect’. 32 players was thrown about, but he didn’t want to comment any more on it. He did say whilst there will be no more wager matches, as he said Infinity Ward are in the mind of how they didn’t copy Zombies, they won’t copy wager matches, but he did say there will be some incorporated ‘similar modes’ to that of wager matches.
He also let slip that ‘they might include teams of three for one mode’ although he stopped into going into any more details, sounding unsure whether it would make the cut. Finally he said there may be ‘up to 23 maps from launch, but they have plans for huge post-support DLC’. This echoes what fourzerotwo said on twitter about Infinity Ward having plans for longer post-launch support.
Whatever the design differences the different teams have, it would be dumb to go back to the old unlock method. Currency made the unlocks in Black Ops much, much better than the older games. Maybe they will make it like Uncharted 2 where one pool of currency is for every game mode (single, co-op, versus).
