The Visual Studio 11 Beta is here: http://www.microsoft.com/visualstudio/11/en-us/downloads. There’s not much more we can add beyond what’s in this post on the Visual Studio blog, but here’s one crucial part of the post, describing how you can give Microsoft feedback:
“If you encounter a bug or an issue, please report it through the Visual Studio, LightSwitch, and Blend Connect sites. We also want to hear your suggestions or feature ideas/improvements so please add your suggestions to UserVoice or vote on other user’s suggestions.”
You can also find related tools, SDKs, and downloads here.
