Beyond that, this match is incredibly hard to predict. However, I'm going to say that R-Truth and King Barrett don't stand a chance. Truth, mainly, because he's literally had nothing going for him and just seems thrown into the match. Barrett because he's been there done that with the IC title several times already, and they would've made someone else "King" if they were going to put the IC title on him.
Ziggler almost falls into the same trap as Barrett, having been a multi-time IC titleholder and it never doing much for his career. Except its clear he's was going to be involved in an interesting storyline with Lana and Rusev. I think his role in the outcome is dependant upon where that story was going to go and the timetable for Rusev's return. If it's only a few months, then I'd consider putting the strap on Ziggler, with Lana as his "good luck charm" and giving him a few successful title defenses against guys like, well, Big Show for one, to make him and the title credible for when Rusev finally returns. At least, that's how I'd book it. In fact, I'd have the match come down to Ziggler, Big Show and Sheamus and have Ziggler defeat both to win the title. As long as Zigs gets successful run and not one where loses non-title matches all the time, I think he could do what they were hoping Daniel Bryan was going to do with the title.
But I'm not booking things. And I think it was pretty clear that before Bryan was hurt, they were building to a summertime feud between him and a heel Sheamus over the Intercontinental Championship. And you know what? I would've been totally on-board with that. (And, quite honestly, they could continue the Sheamus-Ziggler rivalry too as a placeholder until Rusev returns, with Ziggler playing the role of Bryan.) So I'd say the smart money is on Sheamus winning the title.
However, I can't help but notice how much the crowds are really into Ryback lately. You could make the argument that they are into the "Feed Me More" chants, but Daniel Bryan haters could say the same thing about the "Yes" chants. I think WWE has already missed the boat with The Big Guy several times, but he's truly connected with the audience right now and continues to improve in all facets of his game. He's yet to hold championship gold in WWE. I'd like to see a lot more of Ryback vs. Sheamus and some of the other guys in the IC mix. So I say, FEED HIM GOLD.
WINNER: And NEW Intercontinental Champion, Ryback
