There are so many updates coming in the near future, I'd love to hear which one you are most excited about.  I'll give a brief list here, but feel free to include other things also if you are so inclined.

For me, I think that the integration of Silverlight, especially DeepZoom, with ASP.NET is going to be something that can change things.  I think it will transform how we use the web and what the choices are for browsing large amounts of data.
