There's a public page, not in the
apple.com domain, that
might be used to tell whether parts of the pre-release operating system are complete. That page was not a barometer for 10.6 but did seem good for 10.8 and 10.9:
- Snow Leopard (2009-08-28 release, 2009-10-22 observation)
- Mountain Lion (2012-07-10 observation, 2012-07-25 release)
- Mavericks (2013-09-18 observation, 2013-10-22 release).
I can't guess a number of developer previews, and I'll not share the URL (tease!), but the current view of that page shows nothing related to Yosemite so I guess that a release is not imminent. No surprises there
