I know this channel doesn't "officially" go live until Jan 1, but it is already on my cable menu. I have Comcast and I am located in the east bay, so you cable-having folks form around these parts might want to check it out.
Right now, they are showing highlights from the '05 World Series. I have no idea if this is temporary/introductory type of thing or if they are going to be showing highlights until the official launch.
Satisfy your baseball watching jones immediately...and by all means, have some pie while doing so.
