They have offered a spot for Bob but he doesn't want it (yet). Reason being is Bob thinks he has "one more run" and thinks the Hall Of Fame would only be appropriate if he was done for good. So he'll be in one day, it's up to him when. This was confirmed on one of the Legends Roundtables on 24/7.
I think it's probably because the "home" crowd will react the most to it. If you look at old-school regional stuff, when a home-town boy turned on the fans it got more heat than if he was someplace else. The same will apply here.
