i would much prefer them to take all the fan favourites from MW2 and MW4 shake it up a bit and release for only next gen formats.
Although I still have my old 360 and go back to play these maps now and again...although it does take some time to match with the 'not so many' online players.
Yes I know we've been there done that but it was at a time when there was too many cheaters and it ruined the game! Bring the maps back but disable what ruined the playability years ago.
Remember guys, some of those maps were fantastic maps, ones where we would always hope they would pop up in the playlist lobby. One of my all time favs was the house on the hill and the top of the skyscraper.
