I think the promise can be realized in pure UI and AI other than that it is much a-due about nothing. COCOA is a good example of pure UI, as well as some of the JavaScript UI kits. I.E Dojo or YUI. Given that UI objects are well encapsulated via OO is is a natural fit.

Trying to shoehorn all of these technologies into a server side OO framework was becoming way to cumbersome.
