Google is not just limited to these static wallpapers; they are also working on Live wallpapers which will be unveiled soon. Google is also polishing the launcher for upcoming Android 7.0 with new features and better design. Overall many new features and goodies will be disclosed on the release of Nexus 2016 devices.
So, if like me, you cannot wait for the new Nexus handsets to arrive, grab the wallpapers to tide you over the next month or so.
You can download all the wallpapers at once from here
