I'll reserve judgement on Wednesday assuming we'll get details on the OP7 and not the Tv / eco-system project they are working on.
Still all I want is a 6T sized device, decent battery size, no curve screen, along with the pop-up front facing camera and I'll bite. I don't keep phones long enough to worry about moving parts, especially as the standard warranty is 2 years. I just want a phone with near stock Android that doesn't have an ugly notch!
I'd imagine the Pro will have a curved screen along with maybe a bump in screen resolution to something flagship level. If they make me pick between no curved screen and a pop-up camera I won't be happy! lol
