Yes we were concerned about changes also. Talked to the regional sales rep. He did confirm it was going to be a 2019 but they are not allowed to tell us what, if any, changes there are till it is made public.
As far as units sitting waiting for delivery from the factory.... No coach is allowed to leave the facility till it is paid for from the dealer. Also I believe dealers contract with certain delivery companies. If they are back logged that might explain the delay.
