It all boils down to price. Most parents are unwilling to spend $600 for a video gaming console. I'm 48 and have discussed this with many of my friends and they all say that they would never pay that much for a gaming system for their kids. ( Thats why computer gaming has stalled because most people do not want to have to continually upgrade their computers for hundreds of dollars to keep up with the requirements of ever more demanding games. Every 2 years I have to custom build or upgrade a new computer for my son so he can play his video games on optimal settings).

That is why you see continuing sales of PS2 and great sales of the Wii.
