These types of videos are called “Seasonal previews” that will tell us a little about what is coming in the upcoming season (2-3 months)
She also mentioned these videos will not replace their usual promotion teasers and trailers they used to do. Just something extra!
This seasonal preview was supposed to be a surprise, but SimGuruDrake had to give us a little heads up a little earlier than expected due to circumstances that were out of her control. As she states on the forums. These seasonal previews come from the request from many Simmers to have a little more notice of content coming up, so they can decide if they want it, or plan for the future content.
