I seriously doubt they would introduce comfort seats in the rear given their size and complexity. Plus for the 3rd rear seat option I can't see how it would be even possible. (Hopefully that option is still available). Some other minor things that other BMW models have still doesn't seem to have made it's way to the X5 yet which is annoying given the price of a 5.0x-drive, including a lockable center storage console (on 5 series, 7 series) and oil temp gauge (basically on all the other models) instead of the ridiculous fuel efficiency indicator.
