Replying to High Def

So the thought crossed my mind today, why are ski movies not released on high def, ie bluray? Or do companies have plans for the next year or so. Am i missing something? Is producing something on blu ray a lot more difficult than dvd, more expensive? It seems that everything in the ski world is filmed in high def yet is brought down to the level of dvd. I understand the market is currently for dvd, but how difficult would it be to put out some copies on bluray?

I think i would cream myself to see Idea on bluray with 7.1 surround, i think a re release is needed.

thoughts?
