Let the hive mind of Engadget get that for you.
"What is the best wireless surround sound speaker solution? I have a home theater where running wires is just not feasible. I have my own speakers, so I don't want a system that has speakers with integrated wireless. I've done a far amount of research and have only come across a few companies that even offer a reasonable solution: KEF, Kenwood and Rocketfish. Is there anything else out there? What do you recommend? Thank you!"
its going to take time for that drastic a change.
besides, there will always be a consumer market for PHYSICAL media
for some reason, some people actually like owning something with value, you know like gold backing the paper money
eventually, everything will be delivered over the web, until then, looks as tho Blu-ray wins
