In the next version of VSTS ( code named "Rosario" ), we are planning on providing early looks at those bits through Community Technology Preview ( CTP ) releases in a VPC format initially ( first CTP was talked about here ). Nice thing about this is that you can try out the bits without fear of polluting your existing environment. One of the downsides of this approach however, is that the downloads tend to be on the large side, and a few customers have had trouble getting all the bits down in tact. Brian Keller has just written a great blog talking about how to deal with this. Please check this post out.
