Visual Studio 2005 Enterprise Architect Beta 1 (English) will be out on the August 2004 shipment of MSDN Universal... sounds good! 
The first Service Pack for Windows Server 2003 promises a lot of interesting features focused on security aspects of the OS.
What I find interesting is the new Server Roles technology, that can automatically set up security procedures based on the server use with the usage of templates that define settings for servers. You can easily switch the security settings of your machine for the type of server you want (for example if you want to have a mail server, you can plan a Role that automatically close Port 80, turn off IIS and open STMP port 25).
The second great idea is the use of virtual machines to set up separate compartments running Windows 2000 (or Windows NT 4.0) and Windows Server 2003 on a single server. With this feature you can run applications in the Windows Server 2003 environment while continuing to run your old applications in the other partition. This is a way for ensuring backward compatibility and it's an important aspect I think.
This SP1 is really promising!
