Given Adams open support for Ron Paul and his presidential campaign, and the fact Ron Paul is the highest suggested guest speaker again, I'd say it's very likely he'll be on the show again. It's probably only a matter of when the Senator can spare them the time.
I'm not so fussed with Ron Paul myself. Sure, it'd be a huge, redeeming step in the right direction for America if he wins and sticks to his principles, and if he doesn't then people will have to see this parasitic control entity cannot be trusted, no matter whose face is on the cover. That would also be good in the long-term, but will probably herald bad times in the short-term. If he doesn't win, well, America's going to have another 4 years of worse times.
Bitcoin's still the most suggested topic, waiting on that!
