After a long wait, the next version of Microsoft ForeFront Client Security, now called ForeFront Endpoint Protection 2010, is finally available.
You can download it from your TechNet/MSDN subscription or try with the evaluation version available here http://technet.microsoft.com/en-US/evalcenter/ff182914.aspx
A first improvement, you can install it with an executable, no more need to run a command line as it was required with FCS 
.
The server part is now compatible with System Center Configuration Manager 2007 R2 or R3
