When will we get DW Question Answer Plugin get user contributions points/credits and expert page ?

Want to know when can we except to see the user contributions points/credits and expert page that we see on this website now ? I want to make a website which has all these features, so want to know if I buy the DW Simplex theme now, will i get these features later when you add them, or do I need to pay for them again later(if you are planning to add them a premium features) ?
