I suggested in the original post when it was rumors about the guards that it was possible that IW would want out to work with other companies, so again, I totally called it.
But I don't see IW as the problem, mostly because they made 2 great games that reinvented realistic shooters. CoD4 had a fantastic story mode that I rate as one of the best in gaming stories ever. MW2, alternitivly, has a story that's not up to snuff with the first, but compared to the multi-player I played in CoD4, it's largely improved in my mind. So they've got a game with a strong story, and then the next with strong multi-player (though a few more maps or maybe some throwbacks in DLC or updates would be nice)
IW seems to be made up of (or at least was before Activision stepped in and might screw it up) some very creative and intellegent people, who I'm sure don't want to be forever known as a one hit wonder. Plus, with 2 games as strong as those, they might want to break the cycle of sequels and make something new. Which I don't think is a bad idea. I just think that Activision wants to keep their pot of gold full and shoot anyone whose seen the end of the rainbow, and IW definatly has not only seen it but joined them there.
