Since they started putting the HoF out on dvd/airing it on TV, Taker hasn't even appeared at one of them. I mean, clearly, he's backstage saying congrats to people, but he never shows up in a nice tux and watches the show with the rest of the roster.
I just have a hard time seeing him breaking kayfabe for it, even for Bearer. Kane has done an induction before (Pete Rose), has a pretty big connection, and wouldn't break any traditions doing it.
I don't think we'll see Taker at the HoF until he gets inducted.
