They know it, and are planning on upgrading it. I got email about 3 months later telling me it was up and running. I'm a satisfied customer. Hey, if it works, great. That also means that it won't be fielded every-where right away.
Infrastructure certainly takes time to put in place.
The system I'm using was completely re-installed about two months before they made the cable modem service available in my neighborhood. We went from 36 channels to 80 along with the cable modem piggy-backed on top of it.
