By asking the question this way, I don't think you understand how Btrfs development works. But if you check out the git pull for 3.19 you'll see a bunch of patches that pretty much close the feature parity (no pun intended) gap for raid56 and raid0,1,10. But it is an rc, and still needs testing, and even once 3.19 becomes a stable kernel it's new enough code there can always be edge cases. And raid1 has been tested in Btrfs for how many years now? So if you want the same amount of raid6 testing by time it would be however many years that's been from the time 3.19 is released.
