#2 Samoa Joe
There's just something about Samoa Joe interrupting the opening of Raw last week that screams "next big thing". In all reality, Joe, who came to the company a few years ago, probably should have been a top guy by now, but the addition of Bischoff and Heyman as Executive directors should guarantee that it finally happens.
Heyman and Bischoff are absolute magicians at blurring the lines of fiction and reality, which coupled with Joe's ability on the microphone, could be great for WWE television. In fact, between Joe's ability to mow down Superstar after Superstar and his recent face turn, this could finally be the run that puts him at the top.
Whether that ultimately ends up happening or not remains to be seen, and will depend on how far WWE is willing to go with this, but it's not like the opportunity isn't there for them to do something great.
