The issue will be gameplay, not graphics alone. The Wii had a great launch, and helped make the PS3 launch basically fail. But the question will be if the wii has any more great, must have games for it. So far, its basically a console for Wii sports and Zelda-Twilight Princess. Two games won't give it any longevity. They need more fun games. The wii had a great launch because it was fun. It also attracted groups other than teenage boys/hardcore gamers. My worry for the wii is that they won't be able to follow-up on Wii sports. If the Wii has no staying power, it will be because it couldn't do it.

When the PS3 launched, that seemed to be the main selling point, how great the graphics were, and it didn't do so well. Many failed systems had the 'best graphics' in their day, and still failed.
