I've heard now from multiple Dallas SC technicians that the Plano Service Center is nearing completion. They mentioned times to be open ranging from early to late summer 2018. The location is supposed to be next to Classic BMW on Dallas North Tollway and Spring Creek. I'm not sure exactly where, but it sounds like they're refurbishing an existing building. This will be a great addition for those of us in North DFW. Less concrete is that they said Tesla is "considering" (rumor) a service center in Fort Worth and Southlake in the coming years.
