@SunofKratos: That`s a good question. The problem is that they know that AAA sell and bring in more Money and if they don`t develop a AAA game, other will do it. So they might be passing on some serious money.
And as i said, there`s a limit on how much people you have available. For exemple, Ubisoft will be using 8 studios to develop AC 4 or Watch Dogs (can`t remembre which one is it) and that will, in a fiscal year, give them less resources to develop more B games.
One thing`s for sure, something will have to give: either spend more time in development with more resources being used or less time in development with more resources being used. The money spent might be the same in those two situations.
Either way, it will be tough to handle things as they are now, when with each generation, more and more people and money are used to make games.
