Quoted from wtatumjr:There are things that pop up no one foresees - like the light board issue with WOZ. My guess is they want to get a few out in the wild and get reports back from hard normal usage this time.
Didn't JJP say as much a while ago? They wanted to test them before doing the general release. I am assuming/hoping they are building games and setting them aside and will finalise them at some point when they are happy with the testing results and can make whatever changes they need to make. Easier to fix the first 60-80 in the factory if something comes up instead of having them go out to a storm of 'my 8k NIB isn't perfect out of the box it is the end of the world' Let's face it there will be some things that emerge and need adjusting but that's pinball and the more they can minimise it the better.
