I don’t think full wireless is ready for prime time yet, if it ever will be. One of the biggest hurdles is having power to all the wireless speakers. While you might be trading speaker cable, you’ll instead be having AC cords showing, and you may also have extension cords all over trying to reach the speakers if there aren’t any receptacles close by. Also the potential for connectivity, and interference is much greater. More than that though, calibration could be much more difficult because of the signal delay with wireless systems. Especially if some speakers are wireless, and some are not, and even more so when you consider many subs have dsp built in that adds even more signal delay due to processing. I would still just choose good old fashioned wire.
