But isn't CoD5 basically a CoD4 mod? It feels like the exact same game with different weapons, perks, and setting. I personally think Modern Warfare 2 will be just like CoD4, but with different weapons, perks, and setting. Though I hope I'm wrong.
An easy-to-use map maker would be great, especially if they allowed ranking up in servers with custom maps. That would encourage more custom maps, and maybe the game wouldn't get old as fast as CoD5 did.
