I may be mistaken, but I don't think the Bulge battles would be included in the Normandy game or any of it's modules. I think Steve said there would be a completely new CM2 game covering the Battle of the Bulge and other battles along the German frontier.
I can't remember the order, is the CM:Battle of the Bulge game next or is the CM:Modern Temperate Setting next after CM:Normandy? I'm still hoping there is an eastern front game in there somewhere
