You can see why Stern doesnt let people know too much about their upcoming titles too early and how they keep the interest/hype alive by only releasing little bits of info very close to the actual release date. Stern have become masters at keeping interest very very high this way.

WOZ has dragged on like a slow wet rainy week, sure, but if they release a pin which isnt right, it will be alot worse for them in the long run.
I think WOZ owners will forget about the slowness of it all when they unbox the machine on the first night. Its going to be a special machine.
.... is it going to be special enough to get the majority of WOZ buyers lined up for their 2nd title , I think it will.  

in defence of this company compared to stern, well they needed the cash to fund the project, so it sort of had to go the way of selling the product earlier than stern would have, that makes sense especially for a start up business.
it might happen this way for the first few titles i would say then they might be in a position to confidently have an idea of numbers and have money to fund the project later on in the development so it wont have such a long time from announcement to getting the pinball.

It would be hard to predict exactly when its ready, i guess i nthis case they have got it very wrong, they are building a company and a new pinball at the same time. its going to piss people off i guess, but you would have been crazy not to have expected running past a deadline. i think their stupiest part would have actually stated a deadline, they could have done a similar settup to the zombie adventureland pinball game on ordering and they send you the progress of the machine with out saying when, but you can see it being done, its not conventional but clever imo and saves this sort of heartache for them.
