Based on the road map presented above, all the updates that these folks are clamoring about in the new Grand Cherokee are not anything more than a new type of mass testing of mules for the 2017 model year (new vehicle). No different than what the 2014s were compared to the 2013s, though I speculate the differences will be less: e.g. a revised 8 or 9 speed transmission and direct injection may not quite have the same effect as the transitioning from the 5 speed to the 8 speed for the 2014 model year.
I thought the Renegade would effectively replace the Compass and Patriot but it seems that they plan a single replacement for those two. Hard to believe that there are THAT MANY SUV segments.
