Update: A Virtual PC image is also available. 

We've just released the Visual Studio 'Orcas' - January CTP. This is the first of the side-by-side installable CTPs, however, before installing, please read the Release Notes and do not install this on a production machine as this will likely break Visual Studio 2005 when uninstalled.

Besides the new features mentioned previously for Code Analysis, you will also see the following new analysis in this CTP:

New Rules:
Reliability\AvoidCallingProblematicMethods
Globalization\SpecifyStringComparision
Globalization\NormalizeStringsToUppercase
Globalization\UseOrdinalStringComparion
Design\DoNotRaiseExceptionsInUnexpectedLocations
Usage\DoNotRaiseExceptionsInExceptionClauses

Changes to Existing Rules:
IdentifiersShouldHaveCorrectPrefix
 - Now fires on generic type parameters that do not begin with 'T'

CompoundWordsShouldBeCasedCorrectly
IdentifiersShouldBeCasedCorrectly 
UsePreferredTerms
ShortAcronymsShouldBeUppercase
LongAcronymsShouldBePascalCased
IdentifiersShouldNotContainUnderscores 
 - Now fire on assemblies (with externally visible types) and generic type parameters

You will also see a string of better analysis and less noise in existing rules when compared to both Visual Studio 2005 and FxCop 1.35.
