Sony already does some wireless surrounds. They sound like crap.

The problem with wireless speakers is you can't really stream at a high enough bitrate to them to make for decent audio. Plus to really work, they need a plug nearby.

People without a proper room really can't enjoy surround sound which is a shame. There's this whole world of high end home theater equipment most people never get a chance to hear.

I try to show everyone my theater room to get more people excited. Several friends have run out and bought setups after hearing it. It's not too hard to run wires and mount speakers. I genuinely think most people just don't know what they are missing.
