A few people have posted this already, but it's one I've been waiting anxiously for.  New bits with Team System up on MSDN.  If you don't know what team system is yet, then stop living under that damn rock.  If you do, then you have probably been waiting like me. 

Of course this has to come when I'm busy (really busy) at work, and on a holiday weekend.  The wife will be really happy as I nerd out all weekend checking things in and out over and over again.  Ok maybe it needs to wait until next weekend  :)
