Nokia is planning a true PureView Windows Phone, The Verge has learned. Codenamed EOS, sources familiar with Nokia's plans have revealed that the device will include a similar sensor that's found on Nokia's 808 PureView handset. The upgraded sensor for Windows Phone means the EOS will be ranged as a high-end Lumia in the company's range of devices for 2013. We understand that the EOS will be built using aluminum, rather than the typical polycarbonate found on recent Lumia Windows Phones.

AT&T will stock the handset later this year, according to our sources. With an aluminum body and squared edges, the EOS is part of a fresh design cycle for Nokia's Lumia handsets that focuses on a new look. We understand that the company is planning a Lumia 920 replacement in the form of Catwalk that will also include an aluminum body, and another mid-range device expected to debut in early summer. Nokia is also building its own Windows RT tablet that is set to debut in early 2013.
