Based on Sunday night's WWE Night Of Champions pay-per-view, it appears as though Ryback is the new Paul Heyman client that has been rumored for a while now.
As noted previously, there was discussion internally in WWE of using an unknown from NXT as a new "Paul Heyman guy," while the other options were moving either Ryback or Big E. Langston over to the Heyman crew. It appears that WWE is turning Langston babyface, and decided to go with Ryback as Heyman's new client. If that is the case, you can expect it to be confirmed on RAW tonight.
For those who missed it, Ryback came to the aid of Heyman after CM Punk beat Curtis Axel in the Handicap Elimination match, which was also made a no-disqualification rules match during the Night Of Champions Kickoff Show.
