While my Jolla still hasn't shipped, the community isn't sitting still at all. Sailfish has already been ported to Jolla's spiritual predecessor - yes, the Nokia N9 can now run Sailfish OS. The beautify of it all is that you don't even need to remove Harmattan, since it can dual-boot. It's relatively complete too, since GPS, A-GPS, Bluetooth, wifi and 'Calling Functions' are already working.
In addition, Sailfish' first update, version 184.108.40.206 has been detailed in its changelog - it's mostly a bugfix and stability release. So, when the pre-order devices arrive at our doorsteps, we'll have a software update waiting
