Would it be safe to assume that the vast majority of content shown on Discovery and National Geographic was originally filmed in (some sort of) High Definition? Perhaps less so with History due to heavy the use of archive footage.
If so, the likelihood would surely be that their HD channels will ultimately become simulcasts. On the other hand, perhaps that will only happen when there are no more SD broadcasts.
