It would seam that the changing of the type anti-type teaching kills their claim as the Faithful and discreet slave class as it is only a parable according to Peter at Luke 12:41. Obviously I don't think they will ever come out and actually say that the F&DS is just a parable, so when one asks what will the answer be, to spin out of this obvious problem?
Also what do you think is the reason for the change in this teaching? Is it more to do with getting rid of doctrine that can be criticized or could it be that they are trying to make it as though they are really not in control of the congregations so as to say we aren't responsible when the prosecution comes knocking over future pedophile case? Or some thing completely different? Last question, do you think they really thought it through when they decided to drop this type anti type teaching because it does really poke a major hole in their claim of being something they are not?
