Each area is a case by case situation, and while the goal is to bring this service to as many people as possible, we don't know exactly how long that might take, or if this service will come to Oakley just yet. Even in cities that we expand to, there's no guarantee that all homes in a given area will have access; we do this home by home, street by street.
We don't publish our intent to build, or really any kind of information until late in the engineering stage to allow for pre-orders. If you need something beyond what we can currently offer in your area, you might be best served by exploring different options, and checking the forums from time to time, or heading over to www.sonic.com/availability
to see what we have available.
