Here we go… another season of The Challenge is really just around the corner, so I wanted to contribute to the speculation.
Remember, these are just rumors. Vevmo has helped inform this list, and all people on this list are subject to change their availability. There is also a rumored show being filmed in the New York area about life after reality TV. Many of the NY cast members have been contacted for that show, so they may be doing a different show.

Emily Bailey (Road Rules Second Adventure)- Random name to keep you interested
Jamie Larson (Real World: Ex-Plosion)- Not in the final cast, was considered for an older format idea.
Jessica McCain (Real World Portland)- Too busy in school.
Nany Gonzalez (Real World Las Vegas 2)- Declined, despite production asking.

Stop Being Polite 
Jeez, AYTO has its own spin off show right? so why are they still being invited? and what the heck is Stranded With a Million Dollars? is that other lame mtv show thats going to invade the challenge? the challenge continues to decline each season and next season will be no different, i mean rumor has it TJ Lavin will be replaced by some guy named Vitor Cruz.
this some guy named Victor Cruz is bigger than and more known than TJ
Victor Cruz is not going to replace TJ. Let’s put this rumor to rest right now!
What about Derrick K
Vevmo lists Kellyanne as a potential cast member.
Will Sylvia return?
I doesn’t fit with her job schedule this time, so most likely not.
No Jenna C?
Thankfully she is not on this season! ;))
I’m surprised to see Jemmye’s name on the list. I thought she stated she was done with the challenges after Knight’s passing. Must have had a change of heart
