Haven't seen a lot in the news and the website is a little vague as to what they are currently releasing.
I'm confused... the "Next great Moto X Pure" isn't.
The Moto X has been downgraded to a premium mid-range device, the Z is the new flagship... we know a bit from a leak at a Moto employee conference earlier this year:
5.2" FHD Display (big downgrade)
Qualcomm SD660 CPU (nice upgrade)
64GB Storage (only one model we know of)
"SmartCam" and "3D Glass" (no idea what these are yet)
IP68 Water and Dust resistant rating
It is also noted to have a "glass and metal" build of "Unlimited Perfection" build quality. So basically it's a premium mid-ranger with some gimmicks.
We also know it has been delayed due to the inability to get SD660 SoC chips from Qualcomm, but this is effecting more than just Moto.
