WMPU broke the news:
To the benefit of the Windows Phone, this means the device comes with 1 GB RAM as standard, despite only having a 4.5 inch FWVGA screen, and the latest Snapdragon 410 processor running at 1.2 Ghz, which in fact means it is the first Windows Phone with a 64 bit processor and the Adreno 306 GPU.
The device otherwise features 8GB storage, a 4 megapixel rear camera with LED flash, VGA front camera, 2000 mAh battery and most importantly LTE support, which for the 119 Euro price point makes it a steal over the Nokia Lumia 635, which is 40 euro more expensive.
The handset is 9.9mm thick and weighs 147g and will be available in white, blue, purple, green, red and yellow. It will also be available in Dual-SIM.
The Android version has capacitive controls in that large bottom bezel and it seems that the Windows Phone version simply omits these - with the on-screen controls now, the device looks a bit unbalanced. Given that the (right number of) capacitive control spots were already in place, could they not have been re-used, changing the functions/assignments as needed?
All a little odd, plus it's unknown at this point quite what difference a 64 bit processor will make to Windows Phone, especially down at this low end of the spectrum.
There's a video demo, too, by Drwindows.de and in German:
