WWE ID continues to roll out new names, and it's going to continue.
On November 9, WWE revealed Marcus Mathers and Sam Hardway Holloway as the newest ID talent, after filming a segment with William Regal. However, we're told that Regal isn't the only former WWE talent involved. Fightful Select is told that Timothy Thatcher is involved in what is believed to be some sort of coaching or training capacity.
In addition to the names announced, WWE does have some more familiar names in the fold that they're planning to reveal. From what we understand the ID program will also extend to talent who are on the indies who have been signed to major companies in the past, assuming they're a good fit.
Many of these deals were solidified quite a while ago, and some of the talent signed or agreed to have already working AEW or ROH dates since starting those talks.
