Expect that trend to continue. The Fed will probably gradually increase by about 2 basis points over the next two years, provided, of course, that they are right about inflation signals being modest. If inflation truly begins to kick in they will accelerate that.
Why would inflation kick in? Economic growth is deflationary. Greenspan is following dollar policy as he usually does. I know that isn't the official story, but I call it the way I see it.
