Speaking in Konami's latest issue of the company's internal magazine, MGS creator Hideo Kojima has said Metal Gear Solid: Peace Walker will "require hundreds of hours to complete".
He also reiterates that the team from Metal Gear Solid 4 will be seriously involved with the game as well as himself.
"The main team from MGS4 is participating in the development of this title and I am involved in all aspects of the game, ranging from design, direction and scenario writing."
He goes on further to state the game will be a great looking title, despite it being on the PSP.
"Despite being on the PSP, we don't plan on making any compromises with the graphics. The art team is used to producing PS3-level quality and the results will make you wonder if this is really a PSP game."
