I hate to speculate, because anything can happen, but I did make a prediction on another thread. Basically, I tried to imagine what I would do in the ORG's situation.
IMO, you have two choices:
1) Don't show up and rely on your cult-leader status to placate the ignorant sheeple. Tell them it's all lies from your golden microphone in the 144,000 Club studio. ( I would say this is most likely, although the GB or their handlers could finally be comprehending the power of the Information Age and choose option 2.)
2) Show up and admit everything. Blame the watch before you. Explain the difficulty of making sweeping changes to a large organization. Then produce a back-dated set of new procedures, procedures that were to to be released at the next AGM or "special broadcast."
Create the impression that the GB were already working on reform, it's just that the RC happened before the nu-light was released. The GB thought it best to cooperate with the RC, even though they had new policies at the ready. The Australian Branch didn't know, but Jackson did. After all, he is the GB who spearheaded the progressive policy changes.
Finally, play the sympathy card. Jackson would have shown up sooner, but his dad was sick.
The above spin/lies ( theocratic warfare ) would paint the RC as truly satanic/vindictive if they tried to "persecute" the ORG. Can you imagine how evil the RC would be in the eyes of the R&F??? How dare they attack sweet, humble, progressive and proactive Jackson??? He loves kids and his dad is dying!!!
Option #2 is a calculated risk that would make the ORG seem progressive and persecuted. Option #1 is S.O.P for the WTBTS.
