A few days ago I noticed Universal Sports HD in my channel line up. Even though it's part of my cable package tier, I still had to manually activate the channel (it said I would be charged $0.00).
I can't seem to find any articles about a new agreement between US and FiOS, but I can confirm that US is working and is now in full HD, though I'm not sure about standard definition being available.
I'm in the DC area and Universal Sports HD is on channel 596 in my line up. For those interested, there is also live coverage of gymnastics worlds for the next few days on the US channel. Hopefully skating gets similar treatment!
