Dean Hachamovitch, Windows Internet Explorer Corporate Vice President, is keynoter tomorrow and after eight platform previews, one beta, one release candidate and one final version of IE9 it's going to be a must-see.
As well as the above, Joe Belfiore, who oversees Windows Phone Program Management, and is responsible for the design and software product definition will also keynote MIX. He will be accompanied by Scott Guthrie, who is head of Microsoft's .NET Developer Platform and manages the teams who are responsible for Silverlight, Visual Studio and .NET framework technologies.
If nothing else, it's going to be huge and we're going to be right there amid the presentations. We'll be following up this post soon with coverage and discussion to allow your opinions to be voiced. The Keynote is slated to start at 9am PST on Tuesday and you can check the full MIX11 schedule here.
