I see no reason why they would deliberately give their developers unstable builds.
The reason to keep a new UI for Leopard a secret for as long as possible
is very simple: they want as much of a competitive advantage on Microsoft as possible (who are working on Vista SP1 -- and beginning to plan Vienna -- as we speak). Thus, Apple is carefully waiting to unveil the secret elements of Leopard until close to release (say around 60 days), which will probably be late spring, or even early summer.
As for unstable developer releases, c'mon. They're developer releases
. Things are shifting around all the time, and there's going to be glitches, bugs, and quirks. All the current state of seeds indicate that Leopard isn't going to be released in March... but anyone who's been following the seeds has known that for some time now.
