I just saw on Bertrands blog (via DotNetSlackers), that the Ajax Futures Preview 1 is available. It also includes client-side template rendering. I have been waiting to try that feature out to see how it differs from the AjaxDataControls project here at DotNetSlackers. Besides that, it also includes several other features. I will be looking into the client-side template rendering engine and let you know my thoughts.
