"The design philosophy for the PSP as a piece of hardware is a home gaming machine ... If we were gonna make it for PSP, it'd be better for us to make it for a powerful home system instead," he said. The PSP can display console-quality graphics, unlike the DS. It seems as though Itagaki would be far more interested in creating a new game for a home console rather than a portable, especially if it would take a similar amount of effort.
Puzzlingly, he believes that hardcore gamers wouldn't want a Ninja Gaiden game to appear on Sony's handheld. "I think if I were to develop this game on the PSP, most of my fans would be upset." Sorry to prove you wrong Itagaki, but we're more than a little upset that you think that way.
