There's been a lot of talk, chat, flame and troll on the opensolaris lists, despite Oracle having said quite clearly that the release will occur in the first half CY 2010. Most "internal" sources claim that's about the middle of June. Note, this is for the 2010.0x / 2010.1h release. Dev builds are on hold to outside developers and users at b134. They will become available again after the public release of the 2010.0x / 2010.1h release. Again, most "internal" sources claim that the dev builds will resume at b138 or above.
Bit of a bummer, because I've been waiting months to get a fix that is in b135 and well, I'm stuck waiting.
