For Internet-based HD digital downloads to replace BD, the ISPs are going to have to get on board with high-bandwidth downloads.

Look at Comcast introducing 250gb per month limits. Just wait till they get bold and decide to downgrade to the current Canadian limits (60 to 100gb max). Just how many BD-quality HD movies do you think you can get into 60gb per month - not counting all your normal internet usage?

And if they're not BD quality with high-bitrate video and uncompressed audio... well then I don't want them.
