I don't see your point!
Wii is for casual gamers who don't care about game quality (most of them) they are not real gamers, they just bought it because it is cheap and easy to pick up for non gamers!
And for the HD consoles PS3 is OUTSELLING Xbox360 every month isn't it!
For past year PS3 has been outselling 360, so I don't see a real point in your complaint!
So real gamers who play games for their quality and graphics PS3 is better than 360! It used to be 360 but now PS3 is better so it is starting to outsell 360!
So there is nothing wrong with it... there are still few people who prefer 360 but there are getting more and more people who prefer PS3!
