They won't. The decisions are made by people who aren't worried about the loss in revenue as much as being personally blamed for the loss in revenue, and making the games worse for the players looks good on paper when you are presenting it to a room full of people who don't know anything about gaming. This is what happens when you have casinos, an industry that relies on appealing to base instincts, run by MBA's instead of gangsters with cigars. Nobody understands base instincts like gangsters.
If they give us better games, it'll be an accident.
