I still think waggle is a red herring, it's casual friendly content paired with simple controls and a reasonable price point that's giving wii all the success it has now. Look at singstar on the PS2, Phil knew what he was talking about. It's a shame though that Nintendo burned the hardcore gamer bridge in content, performance, functionality, and controls otherwise Wii would be the successor to the PS2... a big tent for all types of games and users.
Unfortunately, Nintendo is one extreme, MS is the other (and desperately trying to escape it), and Sony... well, they're FIVE HUNDRED AND NINETY NINE US DOLLARS, and they probably always will be... though, I guess, they still have a chance if they can get the PS3's price under control and push Home and singstar and similar titles... the point is VARIETY, having a bunch of games for EVERYONE of every type. BUT, since no one's doing that right now, it feels like we've been sent back a generation or two to the 16 bit era and gaming has shrunk... oh well.
