I think that this idea is fanatastic, but not likely to happen. Like a lot of people have mentioned, WaW's time has come and passed. While it is one of my favorite CoD's of all time, you can see how the above is true when you look for zombie lobbies in game. I am very surprised that there are still mods coming out recently like: realism 3.0, malibu drive, DBZ mod. These mods and maps keep the game going and it is because of T4M, and the creators of these maps that WaW survives. I hope that we can get a new, fresh take on some mods/maps by doing a collaboration between mappers on some crazy map pack/mod but I don't know the chances of that happening either. If they do happen however, I have some good ideas for some maps.
