Windows Server 2008 RC0 now available for evaluation and testing
RC0 was released yesterday. You can get your hands on it at http://www.microsoft.com/windowsserver2008/audsel.mspx. You can download an ISO of the product as per usual, and also download a pre-built VHD so you can have it up and running in a Virtual Server environment as fast as your internet connection will let you :-)
There's also a Channel9 video discussing the new features at http://channel9.msdn.com/Showpost.aspx?postid=343783
