Looks like the Pixel phones will co-exist with Nexus. Nexus is not dead.
I imagine what will transpire on the 4th Oct will be remembered for a long time as a turning point in Android history.
Andromeda OS will also run on phones, as well as laptops and tablets, with the Pixel 3 "Bison" laptop being said to launch in Q3 next year being the first Andromeda powered laptop.
So to beef things out:
- Pixel line aimed at the consumer market, premium devices running Android/Andromeda. Sold and branded as "Made by Google" devices.
- Nexus line manufactured by whoever is that year's Nexus OEM. We may even see multiple Nexus OEMs as rumoured earlier in the year. Nexus will remain developer orientated devices, but still available on retail via the Play Store etc.
