so looking at four cores clocked at 2.45 and another clocked at 1.9 not like in this geekbench single core might be 2400 in the end and multi can reach 8000 , will be powerful of course but battery life is what matters here
Moto Z is the most lovely phone ever made (you have to handle on to realise this), beyond the very well conceived snap on modules, the Z is very thin, the camera hump actually looks nice and makes the phone easier to pickup - but, the camera itself is not so good from reviews, and the Z lacks wireless charging. If they can sort both those issues out in the 2017 Z, this will make a great phone.
Hopefully they keep near stock Android, as with past iterations of Z,X,G,E family.
If lenovo tries to put zukUI in Moto, then they are surely going to kill the brand.
And of course a decent Design is expected from Moto design legacy ( not lenovo mobile design team)
