Pretty much the Sims 5 plan so far is making a Sims Online reboot according the CEO Andrew Wilson:

"Typically, what The Sims has done is really focus on fulfilling the motivations of inspiration, escape, creation, self-improvement, and not necessarily focus as much on social interaction and competition."
"As Maxis continues to think about The Sims for a new generation across platforms and a cloud-enabled world, you should imagine that while we will always stay true to our inspiration, escape, creation, self-improvement motivation, that this notion of social interaction and competition - like the kind of things that were actually present in The Sims Online many years ago – will start to become part of the ongoing The Sims experience in the years to come."
