"My role is to run first-party development, and we are always exclusive. Because, in this generation, it costs much more to develop one product, it's just natural for third-party publishers trying to recoup the investment from multiple platforms. I think that's pure economic pressure, pushing most of the third parties to move from some exclusive titles to more multi-platform titles," said Yoshida-san. "Because we know that is the trend, we, as a company, can invest in our first-party studios; in terms of exclusive titles, our role becomes more important."
Yoshida went on to discuss exclusive content that would appear in PlayStation 3 games, something that you wouldn't get on other platforms due to the space on the Blu-ray format; "As far as I can see, with major publishers like Activision and EA, their major titles will be day-and-date with the Xbox 360 and their quality will be really good. And some of the titles, I expect, will have something extra because of the PS3's abilities and the space on the Blu-ray format,".
