He better talk about TNA. I remember he did publicity tours before and all he mentioned was Midget Wrestling and never said a word about TNA. I don't know if that's dumb contracting decisions that prevented him from talking about it, etc... but that was just painful to hear about.
This is the thing... when youre booked for a show like Howard Stern or Piers Morgan, or Today etc etc, they want something juicy or newsworthy. They do not want to talk about a second rate company like TNA and their pay per view.
I wouldnt be surprised if the Hogan sex tape was released around this time on purpose, as a way to get Hogan on television so he can mention TNA wrestling for a moment or two, and then go back to TNA and say "look at how much publicity Im getting you! i'm worth my pay day!"
Honestly, Hogan needs WWE. He just needs to go back there, get a legends contract, be the babe ruth and ride off into the sunset.
The timing is suspect indeed. Weeks after Morgan interviewing the President of Iran, both Morgan and Hogan suddenly and conveniently have a very hot ice-breaker to light up the show and not look shitty in comparison. But even nowadays the first five results of google, e.g. Wiki are big publicity by association. People who forgot Hogan will probably wonder what TNA is when they wiki him.
