More information on the specs of the upcoming flagship Nokia EOS, has leaked via MyNokiaBlog, and if it all turns out to be legitimate, the EOS could end up being one of the best smartphones in a very long time.

According to MyNokiaBlog, Nokia is testing two versions of the EOS, one with a dual core processor, the other with a powerful quad core processor. The quad core processor is the Qualcomm Snapdragon 800; however, Nokia might go with a dual core variant, due to battery life problems that are unsatisfactory.

When it comes to battery life, the source says the EOS will have the same 2,000mAh unit as the Lumia 920. Such a move would be seen as disappointing to many who might need a bigger battery that is capable of lasting a whole day without a charge. However, the main part of the report is about the camera itself, that gorgeous 41-megapixel sharpshooter that first came out on the Nokia 808 PureView smartphone awhile back.

The sensor itself will be an updated version over the 808 PureView, and the source also said there might be two units, one with Xenon flash, the other with LED flash. Furthermore, both units could have the ability to record 2K or 4K videos; however, that might be unlikely as it would add greatly to the price of the EOS.

So far, nothing is known of the display size, but the source did say the device will feature an AMOLED display with the same 1280x768 resolution as the Lumia 920. Other specs include the return of the FM radio, microSD card slot, micro HDMI port and Windows Phone 8 as the operating system of choice.

The launch date is still up in there air, but the Nokia EOS could launch exclusively on AT&T with a worldwide release 1-to-3 months later. It seems Nokia is pulling the same stunt it did with the Lumia 920, by launching the device on only a single carrier in the United States.
