After the SNES era, we saw how Playstation games were quite a bit cheaper than N64 games, but it had nothing to do with Nintendo wanting to make more money per copy: It had to do with the fact that pressing CDs was cheap as dirt, so the game developer would get as much money, per copy, despite a cheaper price.
With the switch to downloadable, we can save even more than that: The cut from the retailer, the distributor, the box manufacturing... You could cut at least $20 from a game, easily, and still get the publisher the same cut.
If you want to talk about game pricing without dealing with fixed non-development costs, you are comparing apples and oranges, on purpose.
