I might be wrong here but the governing body does not have the theological acumen nor the nutsacks to do a name change. They would not be able to justify a name change from a dogma point of view,
It would also cause a major split within the organization, with many people still using the old name. This would not only cause confusion but also deepen their financial difficulties. So unless they have a deep seated death wish I think the name will stay.
They also have 80+ years of brand recognition. (Think what New Coke did to the Coca Cola brand)
Stranger things have happened I'll admit, but a name change would just be suicide... but perhaps deep down in the Governing Body's heart of hearts that is exactly what they want to do.
Cmon G.O.D. Do it... just do it... pull the trigger!
