This certainly can’t be a mistake, but it appears that the Silverlight 3 Beta 1 bits are available for download.  Check out Ars Technica for the links: http://arstechnica.com/microsoft/news/2009/03/silverlight-3-related-bits-start-to-arrive-early.ars.

I’m looking forward to this mornings Keynote when all the features are announced.

More to come…
