I know a lot of my early adopters have been very keen to see pricing and packaging for SQL Server 2005. The good news is details were released today. You can find details at http://www.microsoft.com/sql/spotlight/expandsqlserver.asp. Included within this is a new version - SQL Server Workgroup Edition - great for small departments. See http://www.microsoft.com/sql/2005/s2005ands2000wg.asp.
There is also a nice table calling out the top level differences between the versions at http://www.microsoft.com/sql/2005/productinfo/sql2005features.asp.
I think the most suprising bit for ISVs I am working with will be that Report Builder is only included in the Enterprise Edition of SQL Server. This is an area I will be looking to understand more - as I am sure it will prove to be a hot topic with my ISVs :-)
