After Metal Gear Solid 4, Hideo Kojima began working on new technology for use in his console titles. Given the span of time anticipated for this new technology to become finalized, he felt that a brand-new game could be created. Thus Metal Gear Solid: Peace Walker was born.
IGN has a brief, but informative, Q&A session with Kojima. He talks more about Peace Walker, Metal Gear Solid: Rising, and the new Castlevania title.
"I always said that it [Metal Gear Solid 4] would be the last Metal Gear in which I would be deeply involved," said Kojima. "However, when we started the PSP version there was a lot of confusion within the team and it didn't proceed as I wanted it to. Therefore I thought that I needed to jump in and do Peace Walker."
"This process is taking one to two years," he said. "However, within that timeframe we could do something, and we thought that because of this preparation period we just can't wait and do the preparation – we thought that within that timeframe we could do a PSP version."
