From what I've read over time, I wouldn't hold my breath waiting for Apple to allow stereo streaming of music over Bluetooth. The reason, from what many commentators have expressed, is simple. Apple gets a licensing fee whenever a 3rd party accessory maker creates a product with a dock connector. Allowing streaming over bluetooth would take away a revenue stream from Apple. So, unless Apple develops and patents their own wireless streaming technology, you're probably stuck with wires.
