You are correct that the purpose of the waiting period is to convince those who won't pay to pay, not those who can't pay.
While you don't think that the delay is useful in getting patrons to pledge, Davie clearly does. Now, you can say "screw him, this is a prate site and we take no prisoners, ARRGH!" but that doesn't do anyone any good, because it demotivates the one guy who can create this wonderful game.
Dave Zwei has been a boon to this community, interacting here in spite of the fact that we aren't paying him. He's implemented suggestions that I have made even though I'm not a patron of his. I think the implicit bargain, though, is that we, in turn, refrain from taking a dump in his rice bowl.
So I would vote to respect his two-week delay, much as I want to see the next installment.
