MCPD Upgrade

I passed Exam 70-568 on Friday.  I was surprised about how little of the new features of 3.5 were actually in the exam – only a few questions on LINQ, none on entity framework, etc….  I guess the 4.0 exam might have it?  In any event, I am planning to finish the 3.5 upgrade this Decemeber so I am jumping into WCF with both feet.
