Sony Computer Entertainment America executive VP and co-COO Jack Tretton says a potential 6 to 10 million unit lead for the Xbox 360 isn't "a significant advantage or a significant disadvantage as far as we're concerned."
Tretton told TheStreet.com, "At the end of the day, what you do in the first year, and whether you do 6 or 10 million units does not determine whether you're successful or not. We're looking to sell 100 million-plus worldwide. We're looking to sell 50 million plus in North America."
Microsoft has announced that it expects to sell 10 million Xbox 360 units by the time the PlayStation 3 hits shelves in November.
