Let me give it a shot, very succinctly (although I am constantly being told I am too verbose). Here is what Mark demo'd today at DockerCon:

1) We showed an application deployment, using Docker, of a Windows Server Container (running Node) and a Linux container (running .NET). The exact same Docker client can be used for deployment and managing both.

2) We showed DockerHub integration in Visual Studio Code with intelligent code complete (it auto-fills the DockerHub image you want). Visual Studio Code is a free version of Visual Studio that runs on MAC/Ubuntu: https://code.visualstudio.com/

3) We showed Visual Studio Online continuous integration that packaged and deployed a Docker container using Swarm/Compose on Azure.

4) We showed Azure Marketplace deployment of DockerHub images, that will deploy and configure multiple Docker containers onto Azure Linux VMs (we showed one that deploys both a wordpress and MySQL container on a single Linux host using compose).

5) We showed the Docker Trusted Registry image available to deploy from the Azure Marketplace.

Hopefully that helps (and has removed marketing speak? :)).
