By the time the PS3 launches in November, Microsoft believes it will have sold around 10 million Xbox 360, reaching a threshold, it says, that will help the console stave off the competition. This doesn't bother Sony much.
PlayStation's American boss, Jack Tretton, told business site 'The Street' that Sony has never gone first in the race to launch in each generation and it's not been a problem in the past.
"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," he said.
"We're looking to sell 100 million-plus worldwide. We're looking to sell 50 million plus in North America. So, if a competitor gets to 6 to 10 million worldwide, I would not consider that to be a significant advantage or a significant disadvantage as far as we're concerned."
Tretton also had bitter words about Microsoft, saying that if his company had lost the kind of money that Microsoft had in launching Xbox and now Xbox 360, Sony would have rethought staying involved in games.
