Premium Subscription Planned for The Sims 4?

Over 15 minutes of raw gameplay from The Sims 4
Electronic Arts and Maxis have released a lengthily gameplay movie for The Sims 4, which is currently in development at The Sims Studio and is set to arrive on September 2nd in North America and September 5th in Europe, for PC and Mac. According to this video, it seems that the game will include a Premium membership. Word is: "The Sims 4 Premium: Save on new packs with early access and exclusive items. Become a Premium Member to get early access to 3 new packs, with exclusive items. Your Sims can throw a spooky costume party, camp in the great outdoors, and toast to the new year in style.".
