EA announced Sims 3 is getting a new fog-shrouded world called Midnight Hollow on the 26th of September, which you will be able to purchase for ~$4.50 more than a stuff pack. It includes a few handfuls of gothic/~*~eccentric~*~ items (including, to be fair, some pretty fab-looking steampunk-esque goggles with one of the hairstyles).
Most importantly, though, is the fact that the featured content is called the Savvy Seller's Collection, and it lets you open up your own shop (apparently, as I understood it, by providing you with surfaces like rugs, shelves, etc. that you can place items on to sell). You can set prices, hours, hire cashiers, and decorate to your heart's content. So you who have been sorely missing the business expansion pack that never materialized, this and the restaurant oven may be the closest you're getting.
