Promised I’d be back, albeit a tad on the late side.
Let’s agree that it would have been nice if one of the DJ Staff active on this forum (and credit where credit is due, there are plenty of them and they are actively involved and answering questions, just not this one for some reason) had responded to your question. If only saying they didn’t have the answer right away but were going to find out for you.
I did find some specs, but all they mention is a rate below <x.x% (0,15% if I remember correctly), which - thanks to the “<”-sign - leaves a lot to be answered. Having the same W&F rating as other brands fits within this <x.x% after all. I agree with the OP that in essence anything under those levels is undetectable by the average club guest and as such not a legitimate worry. I do appreciate the curiosity from an engineering perspective though.
@lymbo1990: There are no pictures of the back I guess because there is nothing there. All connections are on the side (we can discuss if that was a clever move, but hey, it’s what Denon decided on). Side pics are clear. Audio and power on one side, led color and brightness and platter torque control on the other. Most other info can be found on the website and docs available. On the deeper technical (and practically less relevant) issues like W&F, see my above comment.
Clearly release dates deserve(d) some more clarity, with everyone waiting for these units 
The VL12 was first spotted a long time ago (under a glass hood), not sure when, but could have been NAMM 2016, so I can see how it’s become a bit of an enigma. It has changed from the earlier models I have seen, one of the clear chances being the (rim of the) platter just to name one.
I had the chance to play with them at the DanceFair in Holland earlier this month and they are very nice. Feel absolutely solid, like you’d expect from Denon. Eye for detail in finishing I would say. Tried the two torque settings (SL1200-ish and high) and the difference is impressive. You can stop the platter but it takes some serious pressure on the rim. I doubt there is much you can throw at it in a regular working DJ setting that it can’t handle. The side outputs/controls suddenly do make a bit more sense when you set up the TTs in battle mode, i.e. turned a quarter turn. Now the power/output connectors are at the back and the other controls on the front.
All in all these round of the Prime offering for all the vinyl/DVS loving DJs out there nicely. If you go with a Prime mixer or hybrid set up with SC5000s, this will be the TT to add. Nothing against it, and it looks awesome with the rest of the components.
Just my two cents, as usual.
p.s. I am quite sure that the Denon guys are working on getting the answers, as I have been witnessing them doing with all the other posts on these brand new forums. Pointing out what is not yet working flawlessly (without being judgemental about it) will no doubt help them improve their service to us, the customers. Being a moderator on a different forum, I know it takes some doing getting “into the groove, rhythm and flow” of things. So far I can only testify to a very willing staff, determined to make this a very good forum. So compliments to them.
