Wii outselling PS3 at GameStop

From an article in the New York Times: Daniel A. DeMatteo, vice chairman and chief operating officer at GameStop, said Thursday that for the first time last week there were PlayStation 3 consoles in stock at hundreds of the company’s 3,700 outlets. Not so for the Wii, which costs $249 and is still flying off shelves.

“We got some in yesterday in really limited supply, and they virtually disappeared,” Mr. DeMatteo said.

Is this just due to the price difference or is it something else?
