It would be a strange move to have Homepin produce the Stern PRO model and not the Premium and LE. Can't see that happening when there are many components outsourced to local US companies (playfields being one that needs to change !). I'd suggest Gary would be looking at smaller runs such as "Woah Nelly" or other similar low run titles.
I've also formed the opinion that Gary will be very interested in how Homepin are producing their games. No doubt a cheaper alternative that local production in the USA - but the fact that Homepin has a factory - before producing the first game - would be enough to attract Gary's attention. From what I'm told, Gary is very receptive with feedback and has an avid interest in what other are doing.
My bet on the first question to Mike - "Who will be doing your clearcoats and what products will you use ?"
