The Wrestling Observer is reporting that on 1/9, prior to the WWE Raw taping, Triple H did in fact call Ric Flair to inform him that The Four Horsemen would be inducted into the 2012 Hall of Fame. Flair was at the Impact tapings at the time, and was told that the announcement would be made later that night on Raw.
It's being said that no one in TNA said anything to Flair about the announcement, and a press release issued by WWE yesterday continued to promote Flair as one of the inductees this year. Pre-Sale information for the Hall of Fame is also listing Flair's name, and Jim Ross has speculated that there's a good chance Flair will appear, so despite his contract status with TNA, it looks like that's what WWE is expecting.
