It appears The Sims 3 Forum member Lilybob has discovered inside the tiny room in the volcano, what looks be a bear skin rug, box of chocolates, a heart shaped bed, and a picnic basket. The game already has a picnic basket available, but perhaps this will be a new basket with new functionality? No one knows yet if any or all of these items will be on The Sims 3 Store, but it could very well be a hint of upcoming items.
A while back a certain survey site listed the 4 items (amongst others) pictured above. A previous post by SimsVIP shows said survey.
