Quoted from Bamatami:
I spoke with a pinball seller/repairer with quite a few years of experience. He says there will definitely be a "pro" model somewhere down the line. I just wanted other opinions. Yes, it means more $$ for Kapow, but if demand is high, they both will be making a lot of $$.
I can't image Stern making a pro version. As its been stated already multiple times, the premium is really the pro but they had to jack the price to cover Kapow licensing so they decided to call it a premium.
Just for the sake of argument, if they wanted to make a less expensive version of the game what could they possibly remove or dumb down? They really couldn't because there's nothing they could take out and still have a decent game left.
