And how many patches are there before support for the game is dropped. Possibly six from my MW2/BO and WAW there were 6. How many DLC's were they? 2-3.

And I don't know what current patch MW3 is on.

It takes time and money to ship out patches. Thats why there a maximum on average six patches per game.
