Speaking to the San Jose Mercury News about sales of both Xbox 360 and Wii, Fils-Aime said, "the question is when" Wii passes rather than if. "That's going to be driven by our own sales rate and getting good software released at the right time. It's clear they are slowing down. It's not unthinkable to see that next year we could surpass their installed base."
In order to do that though, Nintendo needs to bring out some quality Wii titles. Now the launch-period honey moon is coming to an end, and all the company's heavy-hitters are releasing towards the end of the year, the immediate Wii gaming horizon is looking a little light.
