NONE.
This has been discussed extensively the past few weeks, but here goes. A new game should equate new maps. Period. I don't care much for the nostalgia factor. If I wanted to play those maps you listed, I would put my MW3 disc in my PS3 and go crazy. It isn't acceptable where we purchase a game for full retail, plus the price of the season pass only to have a few maps polished or reimagined. What other industry is this practice acceptable? We need to stop asking for polished turds as a consumer base. I want NEW maps for the $110 that I spent on the game.
