The bluetooth connection/protocol is a standard, though. I would be happy to be proved wrong but I don't think it's the case. They didn't mention the issue(i.e. `we fixed this well known issue`) in the keynote either and I doubt they would not take credit for a such achievement. The chip seems designed to handle the connectivity ops (i.e. switch between mac, iphone etc) and noise cancellation. Bluetooth is simply not the right tool for multi-channel quality audio.
