Bob Woodward's upcoming appearance on Larry King tonight is not likely to produce any earth-shatteirng revelations.  King is hardly known as a hard hitting interviewer (what he is known for, other than eight marriages, I've never quite been able to figure out), and Woodward is hardly likely to offer a confession.  However, given the arrogance with which Booby has approached things thus far, he may inadvertently let slip a new piece of information.

Thus, perhaps a very quick roundup of analysis and what we do know (or think we know) might be in order.  I'll give a few items for starters, and other folks can add to this in the comments:

* As spiderleaf noted here, and John Aravosis has noted several times (and I'm sure other folks have as well), Woodward's insistence that he did not tell Downie originally because he was afraid of being subpoenaed by Fitzgerald is chronologically untenable.  That is, since Woodward's conversation occurred several months before there was an independent prosecutor.  And John A. also notes they weren't subpoeaning reporters until May 2004, meaning Booby had almost a full year to fess up before the fear factor could have possibly entered in.
