JB better have a plan for 2017 (year of the 9, potentially). I wouldn't be surprised if they just end up re-releasing a bunch of 9 color ways with minor changes like they did with the Olympic 7 colorway.
I'm a fan of the Retro X. Any colorway is cool with me. My favorite individual shoe overall, at least from my collecting, is the 2000 Concords. Got em for free too!
