Sailfish OS available as a ROM anytime soon?

Recently I've been trying all different types of OS, such as Ubuntu Touch and Firefox OS, and I'm dying to try out Sailfish OS somehow on my Nexus 4. So far I've been dual booting with a neat little tool called MultiROM Manager and that;s worked great, but I'd really like Sailfish OS to come out openly. Is there any idea about when or if that has happened yet? Maybe I'm missing something blatantly obvious, but otherwise I hope not.
