Patrick Logan has one that I'd like to see come true. I'd at least like to see a good hard look at it. I've lived web services, ESB, EDA, and they all have their issues. I'm sure Jini/JavaSpaces has its as well, but perhaps the best of all of them is the right fit (ok REST not web services).
As the industry comes to term with the failure of WS-* we can either start over and reinvent things again or perhaps take a look back at some of the technology that should have been front and center to begin with.
I will post my prediction next week.
