This is an interesting question. If we really do get that separation of UI, then I think web-based frameworks that are heavily based on MVC+ORM will change dramatically... The author does mention Rails as one of the server-side frameworks... but RESTful services are incredibly easy to do with rails. You don't have to use the view tier at all to use rails - you can instruct the controllers to simply provide a RESTful interface to the controller methods and then go off and build whatever separate UI you please... so I could easily still see myself using Rails even if I don't need a view tier (for the moment, this is what I'd do if I had to build a RESTful interface and I didn't have to use Java...). On the Java side, I think that if all I needed to do was create a RESTful interface, I probably wouldn't bother with Struts2 (or SpringMVC, or other java-specific MVC tiers). I probably would just go with CXF or Axis2.
