We hoped and kind of expected a The Sims 4 Announcement today we prepared this The Sims TimeLine from The Sims 1 announcement to the upcoming release of The Sims 4. (Not on scale!)
Some times we can note:
Between the Sims 2 announcement and The Sims 2 Release there were two The Sims Expansion Packs
Between The Sims 3 announcement and release of it there were two Stuff Packs and one Expansion Pack
Between The Sims 4 announcement and the release there will be at least two expansion packs and one stuff pack that we know of right now!
