When Comcast gets on a roll, it gets on a roll. The carrier's latest trio that it has been pushing all over the nation involves FX HD, SPEED HD and FOX News HD. Needless to say, this very threesome has been revealed in Reston, Virginia... sort of, anyway. According to a tipster with a Vista MCE box in the area, these three have shown up on the EPG, though every one is still currently unactivated. It should be noted, however, that the last time he saw this happen, the channels went live within a fortnight. We'll let you do the math from here.
