2.1 provides support for timed launched. Timed launch is not deployment - it refers to when content is promoted into Staging. Prior to promotion, approved change sets sit in their own sandbox that you can view in the Web Project view so that we can preview future states of the website and choose whether to immediately promote or cancel. Deployment is still a separate action a user must take on the snapshot post promotion.
I answered this in a private msg earlier, but what you would need to do is call the deployment service in your workflow. I'd recommend making a copy of our existing WCM workflow and updating it with this. If you like to contribute back, that would be great.
