@RavensFan0710 all, i doubt it.
Anyways, usually EA does have a sale in December, usually before the Steam sales, but this year might be different, as EA brought their games on Steam, so the sales might overlap.
I don't expect Snowy Escape to be in the sale and if it will be, the discount will be minor (10% - 25%). The Eco Lifestyle might have a better discount (33% is my bet, but who knows, i might lose that bet). Sims 4: Star Wars: Journey to Batuu will probably have somwehere between 20 and 33% (most likely towards the 20% side) and Nifty Knitting Stuff along the same lines as the SW game pack.
I hope that the Sims will get in the winter sale, as i am missing two expansion packs and i hope to get at least one of them (Eco Lifestyle and Snowy Escape are my missing ones and i am aiming for the first, with the second being a bonus, if the discount goes higher than my prediction, which i doubt it).
Thus being said, i hope that EA will grant both our wishes.
