Uh, no.
I only play multiplayer COD occasionally, I would not get my moneys worth...
That would stop me buying the game, I don't need a game to be a commitment.
Doesn't seem like the right time to be thinking of implimenting such things, the game has been losing fans to BC2 and MOH could yet make things worse for them(especially if the game is good and doesn't have subscriptions). This seems like a plan that would only be effective at the height of the series success(which may well have passed)and when there aren't strong alternatives(again...this time has passed).
Eh, I dunno. I just think they might be underestimating how discerning the fans are, the IW guys who made the good games have jumped ship and alot of the fanbase is VERY aware of it. MOH could well be the destination for ship jumpers.
