While I would love to see IBM invest more heavily in statistical methods and other things for the Statistics product, it seems to me that integrating open source methods in Python and R makes sense as there is much more to do than any one company can provide - even IBM.  IBM/SPSS provides the architectural features that allow open source to be leveraged and that can't come from the open source community along with some of the statistical and graphical work that is deemed most strategic.

Note that I don't speak for IBM and don't necessarily know what is in the works.

Thanks for the update, Jon. 

At the risk of setting the cat among the pigeons, if IBM had even a little
bit of interest in writing native SPSS code for the methods that currently
require R or Python extension commands, this would not be an issue.  :-|
