Check now and the listing reveals more details of the tested device in question. It seems to be a Tablet and most probably a Lumia 2520 successor with 10.1 inch display with 2560 x 1440 (2K) resolution.
Processor of course is Snapdragon 805 with Adreno 420 processor. The storage mentioned is 55 GB that may mean the device packs 64 GB internal storage.
This is not surprising though, as we have also reported sightings of a new Lumia Tablet with keypad in Zauba data. But with Microsoft already marching ahead with Windows 10 and also expressing their intent to not upgrade existing Windows RT devices to full Windows 10, it may not see light of the day as a Windows RT Tablet as such.
The Windows 10 for Phones & Tablets will support ARM-based devices with display size less than 8-inch only. So, only one possibility of it coming out as a full Windows 10 Tablet remains.
Thanks Nikso for the tip. Cheers!!
