How the Xbox and PS3 can take down the Wii

Microsoft would need to absolutely swamp the 360 with high-quality games designed for people who don't already play games in order to get past the preconception that it has built over the last half-decade, and in doing so there'd be a strong risk of alienating the console's still-huge existing audience.

That's a price Nintendo has already paid with the Wii - a vast slew of samey, gimmicky and low-rent titles have turned a lot of gamers off the console. The sacrifice, so far, has been worth it, but it would be an insane gamble for Microsoft and Sony. Though one might argue that the PS3 is in such bad shape already that it might as well take a risk.
