Microsoft has released a first beta of silverlight 3.0 and with it 17(!) controls from the silverlight toolkit that already was available on codeplex with the previous version of silverlight (2.0 mind you). They also improved the graphics support and added stuff like drop shadows and 3D to the mix. They even added some stuff that I really wanted back when they released version 2.0, so I can’t wait to get my hands dirty on the new framework.
I’m a bit short in time at the moment, but expect more information in the coming few days/weeks.
For now you can find the download here: http://silverlight.net/getstarted/silverlight3/default.aspx
