So the new Ultimate packs now come with the crusader and engineer (when released) classes and not the demolitionist post launch. So guessing down the road we that jumped on the founders Ultimate pack , pre-launch, and got the early (well... almost head start) will latter have to buy the Engineer and Crusader packs to play them? And will they come with their own load out slot since currently there is only 6 but they will total out to 7 classes?
