A lot is being blogged about the availability of VS 2008 SP1 and TFS SP1. It contains fixes and many new features and sound almost too good to be true, but I checked, it's not an April fool's joke 
A little lost in the noise about new features is the fact that .NET Framework 3.5 SP1 will include .NET CLR 2.0 SP2. I've been unable to find anything about this other than this one post by Eric Eilebrecht, but any CLR update is significant.
