Don't think you will get a positive answer on that from the DEVs, it is a part of the testing.
However a cold fact, at least according to the front page of the website, is that the funding is over 30% back from the monthly goal...
I think this question is much more interesting:
How long will the STAFF continue their effort if the response to the needed donations monthly are this low?
I am thinking along the lines "Why should they continue working with this during their sparetime if players aren't showing their appretiation by donating a small sum of money each month" or "Why take this headache if only a few cares"
and no, I am sorry, I have no suggestion how to get players to pay for this wonderful and awsome game and community (if they can't do it by there own free will...)
