The nWo and Batista will all be inducted into the WWE Hall Of Fame class of 2020. This was big news to hear all on the same day, but people close to them knew about it ahead of time.
Denise Salcedo mentioned on Fightful that WWE Hall Of Famers were told about two weeks in advance this time around. Scott Hall, Kevin Nash, Sean Waltman, Hulk Hogan, and Batista all knew about these inductions as well as those in their inner circles.
Obviously, they kept the news quiet until the actual announcements could be made. WWE still got everything lined up and gave them about two weeks to mark off WrestleMania weekend.
It will be interesting to see who WWE decides to pick to fill out the class of 2020. With those five big names going in they might not need very many other huge draws.
