This is kind of weird! In many places, Motorola already updated 2016's Moto Z range to Nougat in December itself, keeping it's reputation for fast updates intact.
I have no idea why, for some, they have postponed it till March???!!
This is how lenovo lose customers, update is late and skip G & E series. Xt 1575 was update b4 nexus 6 last year
Not at all. Moto Z in Canada have Nougat since December. At least on Rogers and Telus carriers.
