Will popular Stack Exchange sites get their own domain?

A Plea For Actual Domain Identities
AFAIK, out of all Stack Exchange sites, only three sites have got dedicated domain name: Stack Overflow, Super User and Server Fault. All others are hosted on a subdomain of stackexchange.com.
I want to know when a subdomain-hosted SE site would get a dedicated domain name. Simply, what's the eligibility criteria for it?
