*Update* - Further information has also suggested this is the device known as "King" or otherwise known as STK100 as noted in this forums post previously.
Just in case the back cover that was suggested to be coming off a Porsche Design BlackBerry 10 device wasn't enough to make you curious, there's now some purported pictures of the device popping up. Shortly after posting up the back cover, over at BlackBerry Vietnam, a couple of shots appeared on the scene seemingly bringing the whole thing closer to reality.
The images are far from being high quality so it's hard to really tell what we're looking at here but if history tells us anything, we're sure to see more of this device pop up in the very near future assuming all is legit with it. Based off of the information, it seems as though this device might be a rebranded BlackBerry Z10, much like how the P'9981 was a rebranded BlackBerry Bold 9900.
