I really doubt you'll see the 10 speed in the MDX in 2018 or 2019, it's going in the top trim Odyssey only for 2018. I would expect the 4th gen MDX to have it along with many other major updates. 2018 will bring only very minor updates.
I don't think the ZF hate is deserved, I have none of the issues the early units had and those have been corrected via software changes. Warranty is a warranty, of course they will support it. Plus the lower trim level Odyssey will still use it, it's going to be part of the Honda line up for some time. Frankly the last thing I'd want is an in-house designed Honda transmission the first year it came out.
