In terms of deployment, you will see a great deal of improvement in the new "Prometheus" suite. Since there is no RadControls folder and all resources are embedded in the assembly, deploying a solution with our controls will be simplified. Furthermore, if you are using more than one control in a project, you will no longer need to add a reference for each specific product. You won't have to worry about skin folders because the skins are in the assembly as well.
All the best,
the Telerik team
