Too much kremlinology.

"Pixel" means this is a Google designed device.

"Nexus" means this is an Android developed with a partner to be a developer device, and to have no crapware and punctual updates.

Android and ChromeOS are very different. Both will continue. In art because a ChromeOS touch device would be as bad at being touch-first as a Windows device. Ne'er the twain shall meet.

Then there's "Google Play Edition" which is... what? Nexus-ish?

And "Silver." And "One."

Did they hire the people from Sun who thought up *beans? Or maybe Microsoft's technology branding guru?
