WWE and TNA are still negotiating regarding Ric Flair appearing at the 2012 WWE Hall of Fame ceremony in Miami. At last word, no deal has been made yet but it’s said that TNA isn’t asking for much in return from WWE. TNA is said to be very open to allowing Flair on WWE TV.
Regarding the negotiations, there’s no word yet on what TNA is asking for. Don’t look for WWE to plug TNA’s product in any way but there will likely be some form of compensation for TNA allowing WWE to use their talent.
A WWE source notes that The Rock’s references to Hulk Hogan and Ric Flair on Monday’s RAW Supershow were an indication that in WWE’s general universe, TNA does not exist.
