VS2008

As I continue my current language-exploring mode, I've noticed that Visual Studio 2008 is becoming a candy store for me.  Is it just me, or do we have an incredible amount of new stuff to play with?  I can't really remember the last time I watched TV, other than Slumdog Millionaire there hasn't been a movie to catch my interest for awhile and when I am done coding, I just want to read a technical book to 'go deeper' in this stuff.  I going to need a geek-intervention soon if I keep it up at this rate!  Now I am looking at the Visual Studio Extensibility Center, uh oh...

Here's my list of installed stuff- Azure SDK, Robotics SDK, Spec # CTP, IronPython Studio, F# CTP, Oslo and M CTP, Parallel Extension for .NET - I got the .NET 4.0 WCF / WF stuff from PDC (looked at in that VPC, don't even know if it's downloadable yet).  I feel like I am 'losing it' on Silverlight 2.0, Silverlight toolkit, AJAX toolkit, AJAX futures - haven't looked at it since PDC.  What am I missing?
