My wife works in the prototype department at Ford, and I don't think that they are working on building 2018 anythings. The programs she is on are still only 2017 models and she hasn't said anything about 2018s being built. But that doesn't mean they are not being built somewhere.
Also, for the camo'd prototype vehicles, they will often only take off the black plastic camo stuff and leave the zebra stripes or spots on because they are are either painted on or they don't take the time to mess with taking vinyl stickers off.
