sync with external gear

What gear are you talking about, specifically?

elektron rytm/ octatrack/ hardware sequencer/ synth. no computer

Unfortunately, no.  

Gotta do it by ear like us old guys ;)

Any plans to implement this in the future?  

Not that I am aware of.

it would be good if a drum machine for example could control the bpm of the xdj-rx(as a slave)

I'm hoping the Toraiz SP-16 will eventually sync the XDJ-RX over ProLink then I can have midi gear synced to DJing.

To be honest, the XDJ-RX is the least-likely of any of our ProLink-capable equipment to incorporate this kind of functionality.

:(

Are there any plans to implement midi clock send in Rekordbox?  I can't be the only one that would like to be able to use Rekordbox to DJ but also use outboard gear?
