I don't see MS getting much out this deal anymore. When they struck it Activision was sitting on the biggest third party game franchise on HD consoles (still is of course) so I have to take the view MS are paying through the nose for those 30 days.
At the time it seemed a good way of pushing 360 over PS3, particularly in US, but now I doubt it matters a jot. In fact if I'm not mistaken the ratio split between 360/PS3 for CoD games has actually changed for the better for PS3 since the deal.
I guess it depends how much money Activision want and whether MS feel they need to have it just to keep their stronghold in US for the franchise and have people expecting the deal to continue to the next consoles.
Try to be reasonable... its easier than you think...
