There won't actually be a Sims 5 because EA is going to 'disrupt the sequel model' by shoving The Sims 4, Project Rene, and two other games into one 'massive Sims platform'
Project Rene, the codename for the next major Sims game, isn't cancelled. In fact, EA will be doing some closed multiplayer testing this fall. But the in-development game we've occasionally called "The Sims 5" isn't actually The Sims 5 at all, it says. Project Rene and The Sims 4 are both going to be part of «the Sims universe» for the foreseeable future.
