Expression Webdesigner will not be in MSDN
The announcement had been made days ago, that Expression Webdesign WILL NOT be available to MSDN suscribers, due to the fact that Expressions is more positioned to designers, rather then developers.
However, if you're from an academic institute, you might be lucky this time round, as Expression Web would be available to the MSDN Acad (and it's only for academics).
Expression has just changed so much since it's first inception. You'd be expecting quite a fair bit of changes, in months to come. Keep a lookout!
