IGN has posted a short interview with BioWare's Tom Ohle concerning their online store and premium Neverwinter Nights modules. You can also find a short description of all three currently available modules in the article. Here's a snip:

IGNPC: Where do you plan on going with the store from here?

We are considering many options for items to sell through the BioWare Store. Full products are certainly a possibility in the future, as are physical goods such as Jade Empire, Dragon Age or other BioWare-branded merchandise. In terms of Neverwinter Nights-specific content, we've still got a fair bit in the works. The fan community surrounding the game is awesome, so we want to keep supporting them as long as we can. We're working with more great talent from that very community, and due to the smaller development costs, we're able to actually be a bit more adventurous (it really sounds like that's supposed to be a pun, but I'm not that clever) with the content we create--we're not limited to formulaic adventures.
