There are posts going around suggesting the Nokia 8 as a listed product on JD.com where Nokia 6 is genuinely on sale.
Whilst this could be an actual listing, the image used here is from ConceptCreator (see below).
Currently the listing has been removed but the images are still present: https://item.jd.hk/1955705911.html
The news going around suggests that whilst it may have originally been destined for the SD835, Sammy snapped up all the initial batches so the Nokia 8 might have the SD 821 instead. Other expected features are those demoed by the ‘Qualcomm’ reference device, e.g. that super electronic image stabilisation feature.
