In an interview with Wired, the Nintendo of America senior vice president of marketing and corporate communications suggests that both Sony and Microsoft have tried to muscle in on Nintendo’s recent success by releasing similar products.

“So far, they haven't spent a lot of time focused on us. Now that we're having some success, they probably will,” he said.

“We can already see some of the things that they've tried. For last year's E3, at the last minute, Sony rushed out their Sixaxis controller as an effort to respond to the Wii remote. We saw Microsoft roll out Viva Piñata as their killer app for the Pokémon set. And neither of those worked really well."

"Part of it is, I think it's not in their DNA," he added. "They're really good at reaching a certain customer, and have a real difficulty understanding how we succeed with the customers that we have.”
