Eventually they will add more HD streams. There are rumours of 3 live HD streams in the works for people within 2200 feet of the VRAD. Time will tell. UvClass 11 - 3 HD at 2200 feet in the near? future.

Within two years, I'd expect to see 3+ live HD streams at any distance up to 3400 feet. They might decide to charge extra for that if they use Pair Bonding or other technology that adds significant cost to deliver 3+ live HD at the maximum distance.
