Another perspective: we ordered a 2015 JGC with the ED and OAP II 8.5 weeks ago. Ship date on factory status sheet was 11/20. It just move to framing status in the factory within the last couple of days. We ordered the diesel because the full drivetrain changes associated with the OAP II weren't available on vehicles with the V6/VVT. (They drop the rear limited-slip differential and the select drive.) The hemi was just too much of a fuel guzzler to make that leap. I'm hoping now that we didn't jump off the cliff with all of the reported problems with the '14 diesels.
The reason for the delay, by the way, was poorly communicated to the dealership. I would have felt much better had I known that I wasn't being ignored.
