I haven't really kept up with SPSS over the years. It turns out they've embraced both Python and R for SPSS programming. Here's a blog posting on why they chose Python.
I'm cooling a little on Python at the moment as I haven't come across an opportunity to use it professionally (yet). However, I think it's interesting that SPSS came to the same conclusion as I did regarding its suitability as a scripting language for the statistical audience.
