Halo 4 DLC release dates leaked?

According to a German Dashboard ‘error’, Halo 4 will be having 3 DLC updates between 10 Decemeber and 1 April.

The packs and the release dates in question are rumored to be:

Crimson Map Pack – 10 Decemeber
Majestic Map Pack – 25 February
Castle Map Pack – 1 April

We’re not sure about the legitimacy of this ‘error’ on the German dashboard, as 343 Industries haven’t offically anounced anything yet. But, it does look like the Halo 4 War Game Pass maybe worth picking up. You know, just incase.
