I think a big point missing here is copy protection. I think this affects future development of any format, and downloads through a locked system is the only way to go, or the best available. Steam, the gamers download bible has got it covered already. Buy the game through their system, download it, and then play it, without a disk! No chance of coping. It's a balance between available technology, and consumer driven advertising. Not news I know! I have a massive DVD collection, and it would be financially inept to try and change them all for Blu-ray, but I must admit that I am buying some of my favourites in the new format, just for the quality and sound. Blu-ray is not a replacement for DVD, but it's storage size and quality make it a well worth partner.
