I just mentioned before that I would rather wait for Explorer to get new transmission. I'm not saying it would come tomorrow, but it should come soon, next few years, it might be even next generation, who knows...
Keeping in mind that Ford currently employs different variations of 6R and 6F transmissions I 'm pretty sure 10R and 9F is going to replace them in near future (my opinion is that Ford long overdue with new tranny).
Update,
Internet source:
http://www.thetruthaboutcars.com/2014/12/exclusive-inside-look-fords-new-10-speed-transmission/
"General Motors has officially partnered up with Ford to use this design in the future (its about 10R tranny). Ford appears to be leading this design effort, and in return GM appears to be leading the design effort for the 9 speed FWD transmissions."
Another source says that Escape and Explorer will get 9-speed:

"Slightly updated for 2015, the fifth-generation Explorer will receive its mid-cycle refresh for 2016, with revisions will include new front and rear fascias. A completely new iteration is due in 2017 for the 2018 model year. Like most Fords, the Explorer too will receive the company’s nine-speed automatic transmission."
