You might not have seen this but a few weeks ago we released a new component poster focusing on Remote Desktop Services in Windows Server 2008 R2. These posters are always popular and are done by an Aussie bloke working for Microsoft in the US. This one focuses on the key technologies in RDS such as Remote Desktop Session Host, Architecture, Remote Desktop Virtualization Host, Licensing, Connection Broker, Web Access, RDS Gateway and RemoteFX which is coming soon with SP1. Check out a screen shot below and a link to download.
You can get the poster from the Microsoft Download centre: http://www.microsoft.com/downloads/en/details.aspx?displaylang=en&FamilyID=9bc943b7-07c5-4335-9df9-20e77ed5032e
