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!"
Looks awesome - but production is scheduled to begin in Q4 2009... so maybe we'll see these in 2010.

That's fine. It'll probably take that long to see more substantial tru2way rollouts anyway.
