Evan Blass of Evleaks fame had earlier leaked names of four Lumia Tablets that were supposed to come after Lumia 2520 and were eventually cancelled. One of them was codenamed Mercury.
Now Even Blass, has posted some images of Microsoft/Nokia Mercury tablet. The device carries the Lumia design language and looks quite similar to Lumia 2520. That Cyan color also reflects the color scheme of the time it may have been planned for. This tablet looks like the successor to Lumia 2520 with a display size of around 10.1”.
Thanks Rajesh for the tip !!
