Grant said we have atleast three more years of sims 4 (2018). So I assumed that Sims 5 comes in 2021 EARLIEST. Like 0% chance of it before 2021.
Now hes not the SP for sims 4 anymore ( happend before sims3/4 aswell)
Hes now secretly working for sims 5. Because of the job offering and other reasons its likely sims 5 developement already began last summer (propably earlier) and they shift focus more and more.
Grant probably becomes senior producer for sims 5 again but in the past this took about 3-6 years I think. (source: Sims community)
Tho I assumed 2021 is the very earliest. I now think sims 5 gets announced somewhen between 2022 and 2025. I dont know if 2021 is still a thing but I think its not impossible just unlikely. Thats just my assumption.
In general I just hope they take more time. Better than launching an unfinished game. I still dont ger why people think sims 5 is a step up from sims 4. It will prob be the worst of the series and become better over the years (patches).
