Hansix has been speculating that DW has been removed far from decision making by excluding him from Board meetings, but perhaps this is not the case because it has not been necessary and DW may be useful to keep involved for a number of things.
For example, Briggs may be "interim" CEO to see if he has the chutzpah and character to establish himself while DW is still on board - ie. DW having been his boss in the past. If he does, I am sure he has a very bright future indeed. If not, the doghouse.
