The Verge reports that "Batman" is actually the internal codename for a new low-end Windows Phone from Nokia, not the Lumia 1320 / 929 as reported by @evleaks. It's believed to sport a large display, be an affordable smartphone and it may fall in the 6xx range. According to sources familiar with Nokia plans, the handset will be placed just above the Lumia 625, a low-cost Windows Phone with the largest display on any Lumia device.
What will the "Batman" Windows Phone feature in terms of specifications? It's said to be a top low-end Windows Phone, but the actual specifications will be similar to the Lumia 625. A 5MP camera will be installed, as well as a front-facing VGA shooter. While this is an affordable Windows Phone, Nokia is said to be planning to ship the device with the new Nokia Camera app, combining both Pro and Smart Cam.
The "Batman" device will join the likes of the Lumia 1520 and a 5-inch Lumia 929 / 1320, which will be unveiled later this month.
So what is the codename for the Lumia 929 /1320 if not "Batman"? Tom Warren from the Verge is confident in the name "Vanquish".
