Silverlight Media Player Plugin

I've always been intrigued on why MSN doesn't use Windows Media Player plug-ins. Well the reason is obvious is not upto par with the ubiquitous offering from Adobe - Flash. Check out all video properties on MSN - they use Flash!. But methinks that's about to change in the next few months. Silverlight is out and being used, albeit in beta form, on some properties.

It's seems to be a good offering, Flash like menus and controls, and using VC-1 codec. So we are going to see good HD previews.
