Nokia is rumored to plan the release of Windows Phone 8 devices as soon as the new platform becomes available later this fall, but it hasn’t provided any official confirmation on the matter.

Recent reports did suggest that the company is already in the testing phase of these devices, and that they would arrive on shelves with the same looks as the current Lumia 800 and Lumia 900 handsets.

If so, many users will be happy, since Nokia’s design for these Windows Phone devices managed to impress a lot.

Until a formal announcement on the matter is made, however, we’ll have to take this with a grain of salt, but that does not prevent enthusiasts from imagining what the upcoming Windows Phone 8 handsets from Nokia might look like.

One of these is the Nokia Lumia Evolution concept phone coming from LokiBartleby / DeviantArt, and it looks pretty amazing, that’s for sure.

In terms of hardware specs, the device could easily pack a 4.5-inch touchscreen display, along with a dual-core application processor, and up to 64GB of internal memory.

After all, Microsoft did confirm that Windows Phone 8 – codenamed Apollo – would offer support for high-end hardware, just as Android and other mobile platforms out there do.

The phone’s camera could be 12-megapixel, most probably packing PureView technology for better photo snapping and video recording.

As a next-generation device, the Lumia Evolution would also offer support for LTE networks, as well as NFC, WiFi, Bluetooth connectivity, and the entire range of usual sensors.

This is only a concept device, of course, but it might easily become reality, especially when taking into consideration the latest advancements in the smartphone industry.

Undoubtedly, if Nokia does manage to bring to shelves Windows Phone 8 handsets that would at least resemble this one, it will be able to regain some of the market share it has been losing during the past few years.
