They have BluRay recorders in Japan already.
But the biggest problem is that it is going to be a format war between HD DVD and BluRay, sort of like Beta vs. VHS.
Anyways, once HD DVD/BluRay players do come out, they aren't going to be cheap, so very few people will have them, so what would be the point in putting ski videos, which do not sell very many copies anyway, on an HD format?
