How long do you think it will be until we see a decline in free submits to link list sites?

We're already seeing them start out on the route that paid partner accounts went on the TGP with lots of them requiring that you 'sign up' for a submitter account before you can list your free sites, do you think that we're going to see the link lists start going the way of the paid to play TGPs in the next few years as the economy gets worse and more and more people jump to adult to make a living?
