Apple has asked developers to test nearly 150 specific areas in order to make the new version of Snow Leopard as clean as possible. Known issues that are outstanding and have yet to be addressed include Core Data output, video corruption, and occasional hangs within System Preferences.
With another release of Snow Leopard pending, I thought we could have a little fun with a poll. Given that it took 88 days for 10.5.2 to hit Software Update after the initial release of Leopard, it may be too soon for another Snow Leopard cub to show up (November 24th would be 88 days). Of course, the past isn't any indication of future Apple OS release dates, so your guess is going to be as good as mine. If we don't have a date range listed that's you think is plausible, let us know what your guess is in the comments.
