Nintendo marketing chief George Harrison recently talked about how Nintendo doesn't pay much attention to the competition.

According to Harrison, PS3 and Xbox 360 are playing tug-of-war with the same customer and trading market share back and forth between each other and that it has no affect on Wii sales.

"We don’t focus a lot on the competition," he told Next Generation. "It appears to us that Sony (PS3) and Microsoft (Xbox 360) are fighting over the same customer and swapping market share. Our performance seems to be independent of those two."

Nintendo is also highly focused on keeping the third party games coming.

"Certainly, there’s a strong lineup of third party titles, and we’re trying to encourage them to make them. But we’re also trying to encourage third parties to take the time and effort to make something unique, not just to sort of throw something out on Wii because the it’s the fast-selling system. I think the ones that have spent the most time in the box are the ones that are going to be the most successful this holiday," he explained.

As was the case last year, there is still a shortage of Wiis on the market this holiday season.
