What do you think of Wii and Sony creating a game council together?

One, it will never happen. In a way, outside of the US, Nintendo and Sony are each other's biggest enemies, seeing as how they both fight for control of the japanese market. At the same time, their business practices don't match. Sony likes to pull out all the stops when it comes to technical proficiency, which usually jacks the prices of their systems. Whereas Nintendo takes a more middle-of the road approach, creating hardware that while usually is weaker than other things on the market, also tries new ideas and comes in at a much lower cost to the consumer. Having said this, the idea of them ever teaming up is very unlikely. Nintendo is doing very well by themselves anyway. There really would't be any incentive for them to do this.
