What I'm getting at is that people are complaining about Kotick not bringing any new ideas to the table... that's not his problem.
But it is his problem. You can buy all you want, but if you don't cultivate you're wasting time, talent and money. Buying can't replace R&D - it isn't a subsitute. It's a compliment or a variation. You buy, you incorporate and you grow. Yes, you shut down what isn't working, but you give it some time. You also let it try to find its way.
Publishers aren't trying to innovate, they're just trying to watch the bottom line. Plenty of companies in the past have started worrying more about immediate numbers than any kind of picture. They almost all end up shut down. If you focus on the numbers today you make bad decisions, often on bad information.
