See the posting of @jatoro at 18/12. He already linked to the forumposting and the Youtube video that shows XDJ1000mk2 is finally there.
I’ve been following this post for a long time 
It is an old NI promise (2018), but difficult to advance. This is a BETA version, with instability and a lot of problems. This HID is difficult to make because of the entire construction of the XDJ’s display and the codes hidden by Pioneer. Nobody says it will come out in the next update. And if I would like you to come,
this and the SC500m 
I only believe it when I see it 
Cheers
Are you one of the beta testers? You seem to know a lot about beta issues😜
I’m not for NI I have friends who are 
so I know a lot about this story 
At the school where I teach I have the setup with the XDJ and I would like the HID with the traktor to work, that’s all.
I also liked the SC500m to be included in the Traktor control. But I love playing with my M’s without control 
For those who don’t know, this HID request from the XDJ 1000mk2 to the Traktor was only the biggest request from the NI Forum during 2018/9 
End of history 
How difficult can it be? Virtual DJ has support for XDJ 1000 MK2 since 2017
For sure it is mk2? Not mk1?
Yes, for sure, see current supported controllers list https://www.virtualdj.com/products/hardware.html?brand=pioneer.
And this article from 2017: https://djtechzone.com/virtual-dj-8-now-supports-pioneer-dj-xdj-1000mk2-xdj-rx/

Another user complaining that his XDJ1000MK2 is working perfect with VDJ, but still not with Serato: https://www.youtube.com/watch?v=n59PgGBQPHw
To get a little more back on topic: For the past few years I thought Virtual DJ would be the second DJ software to support the Denon SC5000 after Serato. I wonder why they can’t make it work yet?
