MTV has still made no firm announcement pertaining to the future of The Real World. Despite nothing official being announced it seems that season 31 is getting a green light.
Individuals who have submitted applications online have been receiving inquiries to continue in the casting process. While this is a very early in the interview process, it is a good sign for the future of the show.
As of right now, filming is slated to take place in October-December, though this is just a tentative date.
