The problem apparently came out early on. The podcaster suggested that a pinball show sale that JJP had some time ago for where the WOZ playfields were being sold for $100 (i think), was likely JJP's way of to get rid of affected stock. The affected playfields would be fine if hung up as a display piece.
Sounds like JJP know exactly what series of WOZs are affected. The podcaster has WOZ LE #11. listen to the podcast - they did say something about the playfields being 'printed' - I'm just not sure if they still are being done that way, with that process being fixed.
