At this point, I can't imagine that they don't have phase 1 of the new park locked down. Rides need R&D time. Designs have to be approved. Ride components need time to to be designed, built and tested. If they are on the verge of starting real construction, they aren't going to wait till October to change a whole section. Not to mention, the target audience for HHN and the new park probably aren't the same.
