If there is a 'The Sims 5' what year should it be announced, and what year should it be released?

If the whole "still three more years of TS4 content" is to be believed, then we'd still have content up to 2021, meaning TS5 would probably be announced next year and release in 2022, a year after the last batch of TS4 content, much like TS2&3 were.

I sincerely hope EA will include some staple content as base game though like Seasons, Toddlers... I don't think anyone else has the patience to wait 3 years after TS5 is released for Seasons etc, especially considering how slow content was/is for TS4.
