Quoted from fnosm:

Great question. The lore has been that the NIB RR's were sold out. JJP has recently announced they are making more RR's. Depending on where you have sourced your game you are most likely getting one of the new run. If you are buying from The Pinball Company or Pinballs.com/Automated Services you may be getting an older, yet still NIB RR.
Review the mfg date on your machine when you get it.
If you have something that was made this summer you are good. If you have something that was made in 2017 or earlier at a minimum you should demand your distributor and JJP provide you with the new 2.0 light boards. You shouldn't pay market price for the old version of the lighting system. I would go so far as to try not to unbox it until you know which version you get.
In general when buying NIB the best protection you can avail yourself of is buying from a proven home use distributor.
(Gets soapbox out of the closet and climbs on it.)
There is much history about dealing with a few large distributors - my advice is to avoid them. Instead deal with the folks below. They will do you right and will shoot you straight.
(In no particular order)
https://www.kingpingames.net - Wisconsin
http://www.pinballstar.com/ - Pennsylvania
https://gameexchange.biz/ - Colorado

Give these people a call, if you get a tool on the phone take your business elsewhere. I guarantee you there are way more good distributors than bad ones.
These machines are expensive and you should be treated with courtesy.
When you get someone you like, research them on Pinside and the web. Get the feedback. Then buy your game.
