I don't think it has worn off, as said earlier when i first heard that there was a WOZ pinball i was shocked. But after seeing it i think it will be a 'fun' pin.
Theme and the LCD seems to be the sticking point and i think we can (mostly) all agree that the pin quality, playablity, reliability will be second to none. For the people that like or don't mind the theme this is THE pin to buy at the moment as far as im concerned. The passion and dedication jack has shown makes me wish i did like the theme as this pin will be a blast to play i believe.
While i have no doubt the road has been hard for the purchasers i believe it will be more than worth the wait.
