In an interview with Gamasutra, Microsoft director of product management for Xbox 360 and Xbox Live Aaron Greenberg, said the Wii console is a novelty and he suggests Wii customers may eventually "graduate" to a Xbox 360:
When asked about Microsoft's initiative to bring more casual gamers to the Xbox 360, and whether it's possible to appeal to 'core' and 'casual' game players in the same box, Greenberg commented specifically:
"Yeah, absolutely. I think that there's a difference in the type of customer that is buying the Wii. When you think about it, there's a difference between trying to be the number one console with nine year old gamers, and being the console that offers the most experiences from 13 to 33.
I think for us, we don't really see the Wii as a direct competitor, we actually very much complement the Wii experience. It's obviously clear that we're going head-to-head with the PS3 in this generation. I think what Xbox will be able to do as well as the Wii is grow the market.
In this generation we're seeing record revenues for the U.S. and globally for the business, and we're seeing more people buying and playing games than ever before, and the Wii is definitely part of that. And as they grow that pie, that benefits us too, because those customers are eventually going to want to graduate to an Xbox 360 experience."
