We've basically "known" for over a year that Google has given up on Daydream. The first indication was the 6-dof controllers for the Lenovo Mirage Solo never making it out of devkit status. The second indication was no other 6-dof Daydream headsets getting released. The near complete lack of any mention of VR at the 2018 I/O conference had all but confirmed it at that point, but the final nail in the coffin was probably when Samsung backpedaled on Daydream support with the S10 release, and Google sticking a Snapdragon 670 in the Pixel 3A, with the 835 being basically the "min spec" these days.

Now, the Pixel 4 doesn't have Daydream support at all, and it's got a beefy 855 in it.
