The SQL Azure Team Blog has an update on some changes in the CTP2.  First and foremost, the product is now feature complete.  Second, if you have been using the October CTP you have now been provisioned over to the go-live production clusters.

Additional Transact-SQL enhancements have been made as well, with Table Value Parameters being the most interesting to me.

PDC 2009 will see lots of discussion about SQL Azure so if you are making the trip to Los Angeles be sure to catch a session.

One more note on SQL Azure, if you are using Visual Studio 2010 beta check out the SQL Azure Explorer on CodePlex.  The add-in gives you the ability to navigate your instance as you would a normal SQL Server instance.  Good stuff!
