Yeah this is quite sad, but as the MW story is over.
I expect them to change things in the next game as I think the series has peaked now.
However they will sell around 75 million copies between MW3, MW2 and Black Ops. So even if MW3 is the peak, it was a beast we will rarely see in gaming.
However I think the spin offs will continue with massive sales like from Halo 3 to Halo Reach. Even with 75% or 50% of MW3 sales, the games will be massive.
