I think he will for a number of reasons.
WWE is clearly pretty invested in him, considering he attacked Rollins and aligned with HHH on his first night. There are two world titles. He's also a really good wrestler and over with the fans. Another thing some people may not have taken into consideration - he's fresh. Goodness I'm just so tired of Reigns/Rollins vs Jericho/Owens that I'll take almost anyone else being in the main event scene. And with this person being talented as Joe, it's a pretty smooth transition. Of course this might not translate to a world championship reign, but people said Punk, Bryan, Styles, and Owens would never win the world title. Again, Joe will be world champion some day.
