There’s rumor of another Sims 2 product that has a release date of Sept 29th 2006. So what is this release? Well, the Australian game store GameHead has this product with only a date and price listed - both The Sims Zone and Planet The Sims have articles linking to the product listing.

But is this just a rumor or a real release from EA/Maxis?

MaxoidMoonBelly had this to say:
“hello! It is a legitimate EA/Sims product, more information will be coming out soon.”
