My guess is that JJ has now run into the same problem that WG in Aus faced - obtaining a viable short term semi-skilled workforce who can build and put together 1000 plus machines in a 6 month timeframe.

They both have the capital to get third parties to manufacture parts - what they don't have is the labour force to assemble said parts into a fully working machine on a mass production scale.

I think that is the reason we have not seen a complete version out in public yet. I am certain that software/gameplay wise it is ready to go but the minute a finished version shows up online, everyone will have JJ on a much stricter completion deadline (and at that stage there will be little other reason than "manufacturing problems".)

One of the reasons that IPB were able to get BBB out the door is that they had a lot of help on their assembly line from the pinball community in the US. That was how they beat the Europe ROHS deadline and got those machines finished.

Can you imagine either WG or JJ asking for help from their respective local pinball communities on an assembly line?
