I wouldn't say soon. Btrfs needs much more robust userspace tools. At the moment, the tools tell you nothing, and recovery is basically impossible. I have lost data several times now. While I had backups since I was using btrfs, I didn't expect to lose data the way that I did. The drive filled up with metadata, and since it didn't have anywhere to rebalance the metadata it couldn't move it, and even if I deleted files it wouldn't make a difference. It happened to me on two occasions. The interesting thing is that btrfs filesystem df showed I only had 80gb total, with a 120gb drive. Decided to go back to xfs for that drive, and I use zfs for my raidz2 array.
