Sheesh, can't we just stick with BluRay for awhile? I am just getting going on my BluRay library! Plus, I think disc based media is doomed in the long run anyway. The Zune video marketplace on Xbox 360 has finally proven to me that you can get BluRay quality video instantly streaming over the internet. There is literally almost no difference between that and a BluRay movie and it's instant-on if you have a good connection. I'm really not a big movie collector, so if things went to all download, I'm good with that.
But already looking into a new proprietary format? Come on, Sony.
