The EOS will offer the same 41MP camera sensor found on the Nokia 808 PureView. But that model came to market powered by Symbian, which is not exactly a thriving platform. The Nokia EOS/Lumia 1020 will be powered by Windows Phone 8 and will probably be an exclusive to AT&T in the states. In fact, similar to the Nokia Lumia 928 which is available only from Verizon, there is the possibility that the EOS will be exclusive to the U.S. and that a different variant of the phone is what will eventually be launched in the U.K.
Smartphone manufacturers have stepped up with the quality of the cameras available on their handsets. Besides the Nokia EOS, the Samsung Galaxy S4 Zoom offers a 16MP camera with a 10X optical zoom and Optical Image Stabilization. And Sony is expected to bring to market the first model in a series of camera-centric phones, with the rumored Sony i1 Honami.
