Latest Zauba records reveal one upcoming Lumia device yet again. The device with code RM-1127 is previously unknown and is listed in Zauba entries with 4.7-inch display and Single-Sim support.
It is hard to tell what it can be, but the way Microsoft has gone about stuffing the low-end to lower mid-range with plethora of devices, it may be just one new addition.

Since the Lumia RM-1127 is only being tested, it might take couple of months for it to release formally so don't have any hopes of seeit it any time soon.
