Microsoft’s Jim Cirone (who is an Architect Evangelist with their DPE group), has written up a nice roadmap to some emerging Microsoft developer oriented technology and tools. One mistake I did see was his release date of Q1 2008 for Katmai (SQL Server 2008). The public release date for Katmai is Q2 2008.
I also noticed that Windows Live Writer is now out of beta and called Windows Live Writer 2008. I have been using various beta versions of this for the last year, and have been very happy with it.
