People or the market do. Companies have learned $400 is the optimum price for a console day one and $60 is the game price day one.
NEO GEO was around $600 when it came out and games were $100 or more. If it had succeeded as the model that is what we'd have today.
Unless the industry as a whole shifts to $70 I think companies independently will try to find add on measures to make beyond the initial $60.
