DTV announced the end of SD transmission several years ago. There are posts that customers have gotten letters indicating they must upgrade to HD equipment due to SD transmission termination. So it certainly appears to me that it's a fact.
And I should have been clear that based on your post HD programs on 101 may be limited. We'll know more when the channel assignments are known.
Maybe the OP will get every HD program on his dome that he desires and maybe not.

Don't get too excited about the idea of HD on 101. There is almost no chance you will get all the channels you pay for from 101. Think about it, why would DTV duplicate HD channels on 101 when they are already being broadcast on 99 or 103? I suspect there will be some HD programming there but I also suspect that most RVer's are going to be disappointed.
