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!"
This only represents the most recent announcements. If you take a look at the agreement with Intel, they've committed to (and had on display at CES) many types of set-top boxes i.e. blu-ray players and tru2way cable boxes (Comcast is already signed up) with widgets integrated, so they're not just for new TVs.
