Christ! I have neither a Blu Ray player or a burner and don't plan on buying either for some time, but I still want him to release it in Blu Ray format rather than one of inferior capacity, and therefore quality!
I'm more than happy to view the disk image on my PC until I get around to buying a player or burner (if I haven't by then) and as others have said, you can shrink it to DVD or AVCHD in the meantime yourselves.
It's the new standard. We're all gonna have these players in our homes eventually. Those who are objecting just because they have to spend longer downloading it or that it'll take up more space on their computers are just being selfish, ungrateful babies. And telling him to release multiple versions is just putting the burden of space/internet bandwidth on him instead of those that'll download it.
