@Splash: While some of the anointed have already received their heavenly reward as of 1918 and onward (per JW doctrine), it would make sense that the understanding that they would 'communicate the truth' to the ones on Earth has been dropped completely when they revised the definition of the "faithful and discreet slave." A study article in 2009 titled The Faithful Steward and Its Governing Body had already paved the path to the current understanding. The article made it crystal clear rank and file anointed have no special status in the congregation and must submit themselves to appointed elders from among the "other sheep." In recent years there hasn't been any consideration of the role the anointed play before receiving their authority during the great tribulation and the Millenial kingdom.
So 1919 does keep its significance in Watchtower eschatology as the year when Jesus supposedly appointed the 'faithful slave' composed of J. F. Rutherford and his team on the top of the Watch Tower Society. This way, the Governing Body ejected, so to speak, Charles Taze Russell of out of the equation of being part of the "slave," thus distancing the current organization further away from its Bible Student roots or loosening the importance of these roots theologically speaking.
