So, one of the keys would be not to let development keep getting more and more expensive and instead trying to find alternative sources to get people interested?

Yep. There was a pretty eye-opening graph (from Factor 5 I think), showing exponential increases in development cost from generation to generation. Revenue isn't increasing exponentially, so something would have to give.
