It sounds like a lot of devices should be updated shortly and I would imaging Google will post factory images soon.
Android Marshmallow Will Begin Rolling Out To The Nexus 5, 6, 7 (2013), 9, And Player On October 5th, Along With AOSP
I want to get this phone, but I want to wait for some more videos and hands-on reviews.
I am concerned about the 810 processor, the radios/signal strength, and sound quality. I am not trying to be negative, but Huawei is an unknown quantity for me.
When I was considering (and ultimately purchased) the Motorola Nexus 6, I had real-world experience with a Moto X 2013. Even though there are differences, I felt like I knew what I was getting---similar Moto radios/hardware/software with a larger screen.
It was also the first Nexus to be unlocked and support all 4 carriers and that was big. I didn't know it would set a precedent for future phones, like the Pure, 5X, and 6P.
I hope this phone sells very well and am hopeful that more phones will continue to be available unlocked and with support for all carriers, but I'm just going to wait for more reviews to come in.
Hopefully, someone will do a side by side comparison with the Nexus 6 and I'll have all the information I need.
Maybe it too will be available on Amazon for $350-$400 this time next year.
