I'm looking forward to the Nexus announcement. Not only because I want to finally see what the phones actually look like instead of speculation, renders and blurry leaked photos, as well as the fabled SD821, but also because of the pricing.
They are in a tough spot this year with the $400 phones being such strong contenders. The OP3, A7 and Honor 8 are great devices in terms of specs and build quality, and they can potentially eat into the traditional Nexus market: high spec phones for Nerds.
So the question is, how do they price them. I can't see the large one being less than $500 with that glass back and all, and also because they have to price it higher than the small one. But then, how do you price the small one? Because at $400, that's Axon 7, OP3 territory, and those are both 5.5" phones that have few compromises. Specially if the 5" starts at 16GB with no microSD slot. And they can't price the 5.5" too low because then it'd basically cannibalize sales of the small one. Will they go for the $600+ market segment again with a premium phone? Last time they tried that stunt that didn't work well for them. The Nexus 6 crashed and burned in terms of price so bad that I got mine for $250 less than a year after its release.
$350 / $450 would be earth shattering but I don't think it's gonna happen.
