How many expansion packs do you think Sims 4 will end up having?

Not many more, i think. I used to play in my laptop with ultra settings and no problem. Now with almost all packs (im still missing 1ep 2gp and 1sp) my laptop fries in ultra. I have to play in medium and def loose a lot of details ?
Of course im not saying they should stop because of people with relatively old laptops. But i think they intended to have the game working in the more kind of machines possible.
For me it could go on and on as long as some issues and bugs are taken care.
