For those who are complaining about how much PPS is profiting because there's no R&D, keep in mind that we have no idea how much royalty they have to pay to WMS. If I had to guess, I would say, at minimum, $500 or maybe 10% of gross sales. R&D cost is fixed, royalty is due on every unit sold. And I'm guessing they had to pay an advance against royalties in the 6 digits.
