I support this. Both my earbuds (for running) and my headset (for listening to music) are Bluetooth and it's awesome.
What Apple may lose in "audiophiles" will be more than made up for by the droves of people who pick up the iPhone that comes with free Bluetooth earbuds...
Free? Since when does Apple give away anything useful. The 6 plus came with probably the slowest charger instead a capable charger like the iPad's. Thats another easy 20 for Apple to charge.
