Will it be possible in the future to use the DJI Focus Remote with the DJI X5 on the OSMO?

Yes, this feature is coming in future! I also cant wait to try it out

My cable arrived & basic function working but needs focus peaking: http://forum.dji.com/thread-55499-1-1.html

Thanks for putting forward this issue again.
We need more of your patience for this new "focus peaking" feature.
Meanwhile, more suggestions or feedback from our people would be appreciated.

Yep patience needed but It's not a new feature. It already works on the X5 - see here on the inspire. http://forum.dji.com/thread-42862-1-1.html

You're right, it's working with the Inspire.
I'm with you and expecting any further update on this feature.
Thanks for your concern.
