Any manufacturer can produce a Daydream-ready phone; ZTE and Asus have already announced theirs. To ensure a good experience, Daydream-ready phones must meet a set of minimum standards. They need consistent performance, low motion-to-photon latency and Android N. Google don't want to harm the Daydream brand by opening it up to phones that won't provide a good VR experience. I wouldn't expect many people to upgrade their phones purely for Daydream, but it may be a factor when their contract is up for renewal. Daydream compatibility is attractive to phone manufacturers who are struggling to differentiate their handsets or offer a compelling reason to choose a high-end device.
