My guess is they've probably received the GSL and are making the final decisions but are doing it in such a way as to generate the most hyped up method.
But that's just a guess..
I think Paizo will ultimately go with 4E and do some pathfinder adventures 4E style. And make a LOT of money, off of their highly professional adventures.
That's funny if it really is the GSL... there was all the hullaboo last week about the site going down and whether that might mean they had the GSL. Maybe they decided to live up to the rumor and take the site down while they actually do decide. (Even though there's no real reason for it.)
