Eurogamer: You mentioned that one of the problems with the PSP was a lack of content. What steps are you taking to ensure that same mistake won't be repeated?
Shuhei Yoshida: As far as we're concerned from a worldwide studios standpoint, right after the launch of PSP we had to shift lots of resources to prepare for the launch of the PS3. That followed closely after the launch of PSP. In retrospect we did it too extreme. We were happy with the launch of PSP. We had lots of games to launch with, but because of the demand of creating games on the new consoles, we shifted resources too much and the coverage for the PSP became weak.
The same thing was happening with third parties as well. The next generation of hardware was launching. Because us and third parties had to shift resources out of the portables, that created the huge issues in terms of the supply of the content.
We learnt the lessons of that experience. We're going to make sure we will have a good, continuous supply of software on PS Vita as we continue to support the PS3 and PS Move.
