Portable Hole Full of Beer has NOT been released yet (I don't know why they have it listed as released...)
It *IS* a real product, Otherwise I've been slaving over this copy of Quark XPress for the past month for no good reason (hell, it's even got artwork and is the first product ever to show off my pathetic cartography talents).
It will be released on Sunday night to RPGnow, although I haven't had any response from their sales personnel in the past couple of days, so it might not actually make it up for download immediately. (It could be that they just aren't taking my promotional material seriously and think I'm trying to play a joke on them too).
In the Portable Hole Full of Beer thread in the D20 Publishers forum you can see a mock-up of the cover as well as some information as to what will be in it.
