The next generation of Windows RT devices may soon be revealed by both Microsoft and Nokia, and while the next Surface is practically confirmed by Nvidia surprise comes in the form of numerous Nokia models that have been pinging AdDuplex servers since the last year?

Logs of this cross-promotion network for Windows Phone and Windows 8 apps have revealed that two Surface devices have been visiting on a regular basis, one named Microsoft Corporation Surface 2 and the other one named Microsoft Surface with Windows 8.1 Pro. The latter variant might as well be the current Surface Pro unit used for Windows 8.1 testing?

On the other hand, AdDuplex recorded a whole range of Nokia devices throughout the past year or so, starting back in October 2012. First device was named RX-107, with models RX-108, 113, 114, 115 and 116. At this point it is unknown whether it is the same exact device in various stages of development or at least two groups of devices (notable lack of models RX-109 through RX-112).

With that said, it seems that Nokia truly plans to join the Windows RT ?party?, as some sources have confirmed to various bloggers and journalists. Many analysts have noted that this move of the Finnish phone manufacturer is ?bizzare and highly surprising? as they should be putting their focus on the smartphone unit range instead. We tend to align on these thoughts. There is, however, another perspective. A possibility that if anyone can help push the Windows RT ecosystem forward, it is Nokia ? especially with various other manufacturers simply giving up on Microsoft?s tablet platform.

Allegedly, the Nokia tablet unit is codenamed Sirius, and should be launching sometime in September. New information comes in accordance to the previous leaks which revealed the shape and overall design language similar to the Nokia Lumia range:

Curiously enough, leaked Nokia tablet photos show Verizon 4G LTE logo on the back side. Could a new exclusivity deal reach Verizon instead of the AT&T this time?

Hardware-wise, unit is supposed to be lighter and thinner than Apple?s iPad, while having a 10.1-inch 1080p screen (with already familiar ClearBlack display tech), 32GB of built-in storage, 2GB of RAM. Sirius is also likely powered by the latest SoC solution from Qualcomm, the Snapdragon 800. Sources also claim that the battery life is going to be comparable to one on the iPad ? around 10 hours of use. Unfortunately, the man who runs AdDuplex – Alan Mendelevich, was unable to find out and confirm much of the hardware data, including the screen resolution. For those interested on data regarding Windows 8/RT devices worldwide, it is worth visiting the AdDuplex blog.
