Two years ago, Motorola publicly promised that all their phones (release after that point) will get at least 2 next Android major OS updates after release and they failed to deliver since. I lost my trust then and promised myself not to buy another Moto. However, I still liked their innovations and producing mid-high ranger phones which can be used in one hand. This year, all the 4 phones they released are 5.5", not to mention that ugly FPS which is positioned too close to the edge with huge bezels. The Moto Zs are even more uglier than the G4 for those mini-bullet holes (I don't know how many sensors they need on the front !). And above everything, the Zs won't be available till September - they could have very well waited another couple months and released them with Android N. Oh and did I mention the ugly huge camera bumps ?
In case you are still wondering, that's a big NO for all the Moto phones released this year. The new Nexus phones can't come soon enough so that I can dump my current Moto.
