I wouldn't get too excited about HD content until next year at the earliest tbh, with the exception of Sky, which does have a good range. Every other source (freesat included) will be pretty sparse (from a number of channels point of view, though they will all do pretty much a full-day simulcast of their main channels in HD). And you have to bear in mind that even then, a lot of the content will have been recorded in SD anyway.............
