I really dont trust these profit figures. There are lots of ways to hide your profit, as to avoid taxation (which is a good thing to do). Nobody would be making games it the chances to loosing money would by 70%.
That's part of publishing anything, be it games, movies, music, comic books, regular books, etc.
You expect the majority (in the case o games 70%) of your product isn't going to make a single dime, and that they'll probably end up costing you money.
You do that expecting to have a hit every now and then that makes enough profit that you can continue to release enough products to cover the spread and thus attain an overall profit.
EVERYTHING, is a bit of a gamble, there is no way to predict before something is released whether it will make a profit or not. There's metrics you can use, useage patterns, consumer preferences, trends, past performances, etc. There are some things that are have a greater chance of success. A George Lucas or Steven Spielberg film for example. A Halo, Metal Gear Solid, or Final Fantasy stand a good chance.
But then, you already hear people complaining of no originality and noone pushing new "innovative" games. Well those same innovative games also almost invariably fail to turn a profit. So should publishers stop greenlighting money for them?
For example, given a game concept of Big rolling ball controlled by player collects objects it runs over and addes them to its mass. Would you greenlight something like that? Yet Katamari games have done relatively well.
So publishers keep greenlighting games that will probably not have financial success in the hopes that they'll find the next profitable franchise or even just have something resonate with the consumer enough to make a onetime profit.
Meanwhile they use the profits from the blockbusters like COD - MW2 in order to greenlight those games you'd like to see publishers try to make but don't often see get made. Because those profits allow them to take those chances.
So yes, the entertainment industry continues to work on the premise that while 70% of product may lose money, the 30% of product that breakeven or make a profit will allow them to keep releasing product and make a profit.
As much as everyone loves to hate Britney Spears, she's done more to bring you the music you actually like, than anything anyone else has done. All because she brought enough money in to the publisher that they could afford to take a chance on unknown artists that might (but probably won't be) profitable.
It's been the way of things for well over a hundred years, and I doubt it's going to change anytime soon.
