Well there are announcements coming left right and center from PDC this year. We've heard about Azure and Microsoft's move to provide cloud services. We hear details of Oslo and Dublin and what they will mean for the future of language developement and modelling.
And then one very important announcment from Microsoft which shows their commitment to Silverlight and related technologies is the announcement that the next version of Office will come with a web enabled version powered by Silverlight. Their is a video posted on Channel 9 about this that shows small demos of Silverlight Word, Excel and One Note. VERY COOL!
This is the future of RIA's and software as a service and I am looking forward to see how Microsoft's competitors continue to compete now that Silverlight and .Net are going cross platform.
