There were reports earlier this summer that Paul Heyman would be getting more superstars to add as "Paul Heyman Guys" for the brand extension. Heyman has since pitched becoming the mouthpiece for Shinsuke Nakamura and Samoa Joe once they're on the main roster. There's no word on whether they will go that route.
Regarding Heyman's new WWE contract, he's expected to work more dates and he will have more creative input in what he does on screen. When negotiating Heyman tried to get a big raise out of WWE officials but it's unknown how much he got. Brock Lesnar was said to have been a major factor as to why WWE got the deal done with Heyman.
