fwiw you can also search for it in the app store and it appears. Or go to the "updates" tab, it's visible in there for me: https://www.dropbox.com/s/f921jp7mjc

(possibly because I already clicked "free upgrade" in the search result? not sure.) This doesn't appear(?) to be an unintentional early leak or anything. I'm installing it on a secondary partition, happy to report if it explodes :) edit: so far so good. I like what I'm seeing for the most part, took very close to 30 minutes from "click install" to "booted into 10.9" on my non-stock SSD. I'm not claiming any responsibility for other people's problems, but it seems to work from here, I'd say go for it if you're feeling adventurous. edit: have to re-install Java, XCode wants to reinstall a few things, re-enable accessibility (shortcat/dterm), all in all similar to a new install. so far all apps work fine.
