It's not the first time that some people get a Sims expansion pack almost a week before the official release. Just before the weekend, raye1forTS2 (from Switzerland) opened a thread on the official BBS in which she announces that she's already received a copy of the Family Fun Stuff pack, which is to be released next week. Several screenshots of the pack are posted in her Yahoo! Album. Read the thread for more information. Thanks to SnootySims and SimsZone for the links.
