Maybe that is how they do it now, but whenever I have ordered a new Jeep in the past, I ordered them in the spring, and mid May is usually the cutoff date with mid June to early July starting production on the upcoming model year. Everytime I have ordered the dealers have told me that to guarantee getting the Jeep I wanted, my order had to be in by mid May.
For instance, my 99 Wrangler was ordered in mid May 98, it started out as an order for a 98. The dealer told me he thought it might be a 99 because the day I ordered it was the cutoff for the current model year (98), and he was right, I didn't get it until September of 98 as one of the first 99 Wranglers they sold. That answer will give you some idea of when to start asking about upcoming changes for the 08 model year.
Typically, Jeep, as do other American auto manufacturers, use the June, July time frame to build inventory, fill "1st kid on the block to have a new one" orders, and have Jeeps ready to go on the lots for the fall introductions. With a 6-8 week order/build time that is typical, the first new ones that show up on the dealer's lots in late August early September have actually been built in June or July. Also keep in mind, auto manufacturers shut down for a week or two during the early summer for tooling switchover, to gear up for the new model year production and to give employees time off.
This is all based on my experience working for Auto dealers and ordering experiences. Maybe with the new plant operations, and robotics they are able do it differently now, but I would call a dealer and ask when is the latest an 07 Wrangler can be ordered and guaranteed of getting what is wanted. That answer may give you some idea of when to start looking into changes for the 08 model year.
