I had the thought that this might be the explanation for the massive availibility at launch - that it's really a 32 pipe card with low yields for all 32 pipes but if they lock 8 of them (of which 1 to 8 are borked), bingo, excellent yields and an ace in the hole (the cards with all 32 pipes working that they're stockpiling somewhere for the ultra launch)
but I haven't really been following the release other then to glance and the review and press release, so i don't know if that's anything even remotely within the relm of possibility.
