There was a video of one of the designers during the unveil and the Jeep guy was extremely, extremely candid and refreshing.
He said "We would all love a 2 door version, but given the JK/JL sells 80/20 4 door/2 door (which is the opposite of what Jeep predicted in 2007 when the JKU came out), there will never be a business case to make a 2 door JT.
He said there never will be one, and also confirmed there will never be a V8 from the factory (becuase crash safety)
It's been delayed again, sounds like it will be in the JL and JT for 2020
I hope they use the time to fix the design issues with the 3.0 ecoDiesel (bottom end bearings, longevity)
