GameFAQs.com and a Swedish retailer under the name of discshop.se have listed “The Sims 4 Seasons” to be released on June 22nd.
But just remember this is a rumour since the pack has not yet been announced by the team. So the pack and the release date may not toally be correct since the team has not yet announced it.
We have just under 6 hours left to see what the pack is so we will have you covered, but in mean time this is all just speculations.
