Quoted from clg: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.
Spoke with Jen again today about extras on the pin. I opted for the red Smaug and that I was too late for any playfield mods. This is exactly what is happening. There are 80+ (one is mine) that are already assembled and when they get the go ahead from their testers, they'll be boxed up and shipped right out. Like you said, easier to deal with any issues while there still at the factory. She mentioned that the testing has been so positive thus far, that they may be shipping them as early as next week!
