Starting from the left, that handset in question is said to be the Motorola Droid Mini, presumably a smaller and potentially less powerful phone than the Motorola Droid. The phone second from the left is said to be the new Moto G which we guess kind of corroborates the earlier leaked photos/renders.
The third phone from the left is the Motorola Droid whose photo was leaked yesterday and presumably destined for Verizon due to the Droid branding. Last but not least is the phone on the right which is supposed to be the next-gen Moto X. Interestingly enough all the phones are depicted with black covers which is admittedly a bit boring, but presumably the final product will be more colorful.
As it stands, the specs of the devices remain unknown and unconfirmed yet. It is unclear as to when Motorola will unveil all their new devices but it’s something we will be keeping an eye out for. Until we hear otherwise, do take it with a grain of salt for now.
