I talked to a local dealer (Indiana) over the weekend about ordering a CRD. Overall, they were obviously aware of the '14s and the diesel option but were still very behind this board in terms of any specifics.
Anyhow, I just received this email from the dealer. I don't think it's accurate, I'm just sharing this so people realize what a great resource this board is:
I just found out that we will be able to order a diesel Gr. Cherokee the last quarter of the year ( sept.) I will call or email when we can order them."
