Google launches new device every year as they've already launched the Nexus 4, Nexus 5, Nexus 5x and 6P in previous years. They may replace the Nexus series with the Pixel series.
Nest leaked the new Pixel device in the TV commercial in the Netherlands. Check the video at the end.
Both of these devices have an aluminium finish which means they've reduced the weight. The top rear panel is made of glass. Also, there is a fingerprint sensor at the back.
We are expecting these two features in upcoming Pixel devices:
1) New boot screen.
2) Wireless charging.
The Pixel 5 is supposed to be the Sailfish device while Pixel XL is expected to be the Marlin. Google just made a website related to it.
