(1) Jack knows what he's doing. The hardware has universally been considered a cut above. There is absolutely no reason to think the software won't eventually be just as brilliant. Jack's talent pool are PROVEN pinball designers and programmers.
(2) Remember they're not just building a single design. They're building an entire company from the ground up. Distribution network, parts suppliers, assembly line design, inventories, circuit board designs, operating system creation. That's just off the top of my head. That's ALL before designing a single thing SPECIFICALLY for WOZ - not a ramp, not a bolt, not even a backglass sketch. And they're trying to build in ways no one has ever done before, like the LCD. (Cough, cough...or stereo sound), so they're inventing the wheel in a lot of ways.
Frankly, I'm amazed they are as far as they've come. Even to the point of securing a big time license for JJP #2, further illustrating that they're in it for the long haul. That they won't produce a shoddy pin #1 because they need to secure a good reputation because they already have sunk in money for the Hobbit.
(3) I didn't so much buy a deadline, but bought a chance to own a Very Special Pin, filled with things never done before. I am COMPLETELY okay with waiting longer for the sake of perfecting all the innovation WOZ represents. Would rather wait a little longer, heck a LOT longer, for a special pin done right but late, rather than have a mediocre sameoldsameold pin on time. I recognize that opinion isn't universal, but that was the mindset I went into with this purchase: something special, but inherently full of unknowns with production timeline as a result. So no surprises, no worries.
I want JJP to spend their resources on making the pin better, not faster.
(4) Ask yourself honestly: is the state of pinball HEALTHIER or LESS HEALTHY since JJP was formed? I think pretty clearly the answer is HEALTHIER, even if you don't own/intend to own a JJP.
