@kurisu Check material.io for the design language upgrade on itself, and see the tons of stuff that Google has been releasing around the I/O (the event's app, Gmail, Google News, Google Drive, Google Pay, Google Tasks, Google Account Settings, Google Home, etc.) as well as Android P to see *their* version of it.
In particular, Google designs are based on the use of white, black and blue along with Google Sans and an abundant use of fully rounded corners.
