Well, when you watch the gameplay trailer of MW3 and stop at 0:49 you can see something which looks like tactical insertions.
Personally, I want it back because there will be boosters anyway, no matter if there is a nuke as killstreak or not. I mean, the feeling, while activating the nuke you got (legit) and win the game just because of yourself, was just awesome

If they are smart enough, they may add something against those boosters.
