I just noticed on the Sims 3 homepage that there will be a Live Broadcast about Seasons and the next SP 70's 80's and 90's stuff taking place at 10:00am PST on November 8th. This is what it says on the Origin website:
Join us on November 8th, 2012 at 10:00am PST for The Sims 3 Seasons Live Broadcast! Take a deep dive in to the game with another exciting demo where we’ll be showing off winter in all its glory, and ask your most burning questions for a chance to have the producers answer them live! We will also be debuting our groovy new stuff pack, The Sims 3 70s, 80s, & 90s Stuff! See us warp Sims back in time to bellbottoms, spandex shorts, and denim jackets to play with all new objects from the past. Tune in Nov 8th to discover new ways to play with snowflakes, igloos, mustaches, and plaid!
