I'm right there with ya man. I *just* bought my 2017 JKU in July of this year... I already want an upgrade! Talk about throwing money away! Like you, I am very interested in that diesel engine! I think that maybe waiting about a year for the all the models and trim levels to come out will help you make the decision. And, I am sure I am not the first person to say this but, if you plan on doing after-market upgrades, going with a sport is a much smarter idea versus the rubicon, in terms of money you will save.I just can't decide what to get right now! Personally, I felt like I made a mistake with my JK not getting a Rubicon. So, that part of me is set. But now with the JL vs JLU I don't know what I should get. I really want the extra cargo room that the JLU provides, but that's going to add up to an expensive rig... now when my wife finishes up med school, maybe I trade in the JL and get a JLU diesel? Does that sound dumb? Don't want to be throwing money away. Lol.
