From Somasegar's WebLog: Listening to your feedback - Expression and MSDN
"I am pleased to say that we will be making Expression Web available starting today to all MSDN Premium subscribers. We will also make Expression Blend available to MSDN Premium subscribers shortly after the Expression Studio release later in Q2 2007. Expression Blend and Expression Web are intended to help creative professionals collaborate with developers to create rich user experiences for the Web, Windows Vista applications and beyond, which means we need to make sure both tools are readily available to our developer community.
The decision extends to all MSDN Premium subscribers, including those with Visual Studio Professional and Visual Studio Team Edition’s. For customers that have premium subscriptions to Visual Studio Team Suite, we will be making the entire Expression Studio available to them."
