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!"
If SEGA didn't have it in the first place how can it be a loss??? If they first acquired it THEN someone took it you could call that a loss. Saying you lost something you never had seems a bit conceited to me.
