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!"
I will keep an eye on Target. There may have been nothing to it, but during the Blu-ray press conference someone said (I think it was some studio guy) Target was going exclusive. Maybe he was mis-quoted, or maybe he mis-spoke, but it's still interesting to see what happens there.
