what happened to the falcon?

Halo 4 Falcons

this image clearly shows falcons flying in the background near the chiefs assault rifle, this image was when we were anxiously waiting a few more months for ths games release yet i was extremely disappointed that the falcon is presently absent from Halo 4. will it come in later dlc or was this image and the possibility of it returning a lie?

I believe they are adding it with the next map pack.
