I don't think Treyarch will ever make a return of the Wunderwaffe DG-2 on future zombie maps. If you listen to the radio message in the Black Ops version of Shi No Numa, the Wunderwaffe overloaded the teleporter when the 4 characters are trying to use the teleporter. Instead, when they used it, it sends them into the future. The Wunderwaffe was not teleported with the characters because of the overload, meaning that the Wunderwaffe was destroyed. Because of that, the new wonder weapon, the Thundergun, replaced it. So, really, the Wunderwaffe DG-2 will not return. So, for Map Pack 2, I think Treyarch has three options for the new Zombie map: Keep the Thundergun, introduce a new Wonder Weapon or do both.

And about the idea for a new perk, I don't think Treyarch would put a 6th perk into the new Zombie map. I think five perk is enough.
