Just saw that Microsoft unveilled the official name of the technology formerly known as WPF/E:
Silverlight. All related downloads like the browser plugins, the SDK and the samples have been renamed accordingly. Strange, I would have expected such at announcement at MiX, but I guess there will be other major announcements then

If you want to see Silverlight in action prior to MiX, visit the
Munich .NET User Group this Thursday where I will speak about it, as usual with lots of demos.
