If Google was smart they'd rebrand all of HTC's phones to Google. Keep the Pixel as the top of the line and bring in a few lines under it, They could even reuse Nexus for mid-range phones. Google has the good mindshare that HTC doesn't. Maybe they're waiting until they have some products that Google had design influence over first, that sounds like a brilliant move. Maybe they'll just do what they did with Moto.
