Does anyone's cable TV provider offer HDTV?


Does anyone know if cable TV providers will soon offer boxes capable of HDTV? Do youy already have such a service in your area? (My service just switched from AT&T Broadband to Comcast, but I still just have the basic CATV box). Many prime time network shows and sporting events will be broadcast in HDTV this year. I do not want to switch to satellite if cable TV will soon catch up because my internet access comes in over the same cable and it is very convenient to use a simple splitter, and then be billed for both services by the same company.

Comcast will have HDTV soon in the Michigan area, I don't know about other areas though.
Here in NYC, Time Warner has a digital cable package that includes a HDTV set-top converting box for no extra charge. I think they're carrying four or five network channels with limited HDTV content as well as HD HBO and Showtime channels. Here abouts, you can currently get more HD programming over cable than on satellite. Been eyeing it myself, but have to get a TV that can show the stuff first....
Follow-up... Comcast says that they will soon offer HBO and Showtime in HDTV here in the Atlanta area. My concern is that the 3 major networks are offering many of their prime time programs and sports in HDTV in 2003, but Comcast has only mentioned the 2 movie cahnnels so far.
