Comcast isn't known for adding in vast quantities of high-definition channels in Jacksonville, but rather, it prefers to spice up the northern Florida city with a few at a time
-- to keep things "interesting," we presume. Whatever the case, a local has just noticed that the carrier has added in Fox News HD, SPEED HD and FX HD, making them the first newcomers in the area since late June
. Hang tight Jacksonville, maybe you'll get a whopping four new ones next time.
