After all the waiting, you might have expected some sort of grand announcement, like email or a customer letter or a notice on the Comcast web site. Instead, self-discovery seems to be the main way Comcast customers in Bremerton will learn that the “coming soon” HD channels are actually here. In my case, I was checking the channel lineup in the Comcast Guide yesterday afternoon just before President Obama’s speech on Afghanistan and there they were: Fox News, CNN, MSNBC, and about 15 others, all in high definition and all occupying a previously unused block of channels starting at about 650. 650! No wonder Comcast complains about bandwidth problems.
The tide goes out, but it comes back in again.

Wonder how long they have been there. Time Warner is always sending out emails. Maybe you unsubscribed to Comcast’s at some point
