The console that makes the most money is the winner?
Just becuase nintendo made the most money this generation doesn't help them with making money for the next one. The company who spread the most influence is the company that is the real winner. Do you really believe MS enterd this generation losing money for no reason? It was so that they could make a crap load more money the next time around.
Just becuase Nintendo made money this generation doesn't mean it isn't going to screw them in the long run. The console battles have always been fuaght in antisipation of the next generation. Think about it, if you lose market share, you are losing potential money for the next gen. That is why nintendo needed a revolution. They saw that there near monopoly was completly gone and needed a way to continue making money. The only way they would be able to do that was to stay in the console making busness becuase that is where the big money is at.
In the end a company is about making money and securing the chance to make money in the future.
It costs money to make make money.
