Thanks to Scott Davis of aboutGroovy for pointing this out.  In an InfoQ interview with Keith Donald and Jeremy Grelle, Groovy and Grails seems to figure prominently in the next version of Spring Web Flow 2.1.

I think you’ll also see us explore scripting languages as means of defining control flow in the 2.1 release. Grails, which builds on the Web Flow 2 engine, has already shown that a Groovy-based flow definition language is viable, and we are working with Graeme on incorporating his GroovyFlowBuilder back into Web Flow proper. In addition, I think there is real opportunity in broadening the flow definition language into what I call a “site definition language”, where you can define an entire site macrostructure declaratively, where some of the site elements are flows. Jesse James Garrett’s Visual Vocabulary is really an inspiration for some of these ideas, and I think there is a lot of interesting work to do in this area.
