As far as we know he didn't even organize his own succession, which is one of the most basic responsibilities of a CEO of a multinational. Even when he knew he was terminally ill. So I don't see much hope that he organized the rest of Apple as some great enduring company either.
Steve didn't make his succession plans public, but that doesn't mean they didn't exist. Publicly announcing your succession plan has no upside and lots of downside. Just ask Jay Leno or Brett Favre.
