Chris Pendleton notes on his blog that Microsoft has released trueSpace for Virtual Earth 3D for free. I think most of us thought this would be the eventual result of Microsoft’s acquisition of Caligari so it shouldn’t be too much of a surprise.

Unless you purchase the Pro version of Google SketchUp (and its ability to export more format types), you can’t easily migrate your models to Virtual Earth. Such a shame that Microsoft didn’t make the migration easier.
If only Microsoft put on a little Google this morning we’d have some interoperability
