I think you will very much see more products that are fully daz compatible in the future and very soon more daz studio exclusive products.
Now that so many products in the daz store are studio compatible the daz user part of the market (up to 32% per a poll I saw this week) is going to start expecting it standard in the products they purchase and more vendors will have to start checking to see that products work in both programs if they want that to appeal to that part of the market. 
Also, clothing dynamics should go live sooner than later and products that are intended for that plugin. The part of the plug in that simply uses the clothes will be free while the parts to create products and change settings will pay for from what I read.  All of those products will be Daz only in all likely hood based on the fact that merchants preset the fabric information for easier use by the end user. Once people are use to a larger variety of daz only products you can expect the sale for them to expand as the number of daz users continues to grow.
