After the acquisition of Motorola by Lenovo, company had changed many nomenclature series for Moto devices. Firstly, they removed Motorola and kept the name Moto. It seems like Sony and Moto has interchanged the X and Z each other. From the next Moto onwards, the devices will be named as Moto Z, instead of Moto X. There were many leaks regarding the next Moto device, from teasers to live images.
Now some live images of Motorola Moto Z have been leaked via Google+ handle +helloMotoHK, along with some replaceable shell covers for the device named as StyleMods. The device shown in leaked image is same as the previously leaked pictures. The StyleMod cases are variant types made of leather (brown tan), wood (wood shaded colors) and Ballistic nylon (red). The wooden made cases are first time ever in Moto X devices.
But the hard cases hides the speaker grill at the bottom rear panel. It is not clear that whther the device would be modular like LG G5 or not. Wait for the official announcement.
