Trust me, as one who lived through Laser Disc, D-VHS, Divx, etc, you will still see HD-DVD releases for at least the next year to 2 years though in vastly dwindling numbers. There are enough HD-DVD owners out there and players to still sale, for Universal and Paramount to milk for a while yet.
Yes - but as I pointed out, Laserdisc couldn't play DVDs (except for that one Pioneer player). And no, once Divx pulled the plug there were no more releases.
This is going to be different. Studios are not going to go triple format. For goodness sake, Universal and Paramount were barely releasing anything BEFORE the format died. No one is going to go to the trouble of two masters, or to cripple the BD encoding to fit onto an HD-DL if they want to go BD-50.
This is way more over than most HD supporters think it is.
