Here are a few things you can look forward to over the remainder of MW3's life-span:
- A patch for lag is coming.
- A patch for spawns is coming.
- Face Off maps will get alternative game modes each weekend.
- The DLC calendar was just updated and it probably now shows the final DLC count: 12 maps, 8 missions, 5 Face Off maps, and 1 game mode (Chaos Mode).
Also, I think it's safe to assume that the patches for lag and spawns are as much for MW3 as they are for IW's next game.
