I think that Rowlf was announced as being retired, but they reneged on it recently in small ways, like his one-word cameo in the Garth Brooks episode and his triumphant return in the live TMS at the Hollywood Palace (which brought forth a non-stop chorus of "Keep doing Rowlf!" from fans to Bill Baretta.) In other words, the info was at one point true but now has become obviously outdated.
They still list John Cleese as playing R in the next James Bond film despite the official site and every other news site now being on the ball with him officially being the new Q. Really burns my biscuits. I shall submit the info to them ONCE AGAIN!
