From April 2007 PSM: Director Yosuke Hayashi:
We don't really take the hardware sales into account. I mean, we didn't do that back in the days of the Xbox. Can you imagine? What if some one said, "why did you bring out Dead or Alive 3 if you had no idea if the Xbox was going to sell or not?" Thats not the philosophy at Team Ninja. Our philosophy is that no matter how small the install base of hardware is, there is an install base.
I think developers who use the hardware sales numbers as an excuse, it's because they don't really have faith in their product. They want to wait untill the hardware has enough units...because they know that their software can't stand on it's own. They need to have millions of installed users so that people will walk into a store and maybe buy their game by mistake. Or they figure,"Hey, if theres a 100,000,000 people that use the system, some of them have to buy our game." For us, were total opposite. We have faith that what we make is compelling enough that if even one more person, or two more people, or a hundred more people, or a thousand more people get their hands on the game, thats good enough for us because were confident that theyre going to have a good experience. It doesn't matter how much hardware is out there.
