Honestly with Motorolas X and G. I don't think Moto going the way as everyone else is. I think the X-Play might have a 1080p screen because it'll be a phablet. I hope Moto expands on the X8 and does not get rid of what they done. Custom processors are almsot always better than straight out of factory. The cameras fine for me, but I guess to shut people up, they'll keep working on it.
It's like buying a s4 this year ("great specs, great beast") than the s5 out next year. Yes theres going to be a better X but not for a while, theres going to be a better n6. Late next year for both probably. Buy now while you have time.
