Konami appears to be gauging interest in a PS3 version of PSP game Metal Gear Solid: Peace Walker.
Gamepro said publisher reps were quizzing attendees of a recent press event about the allure of Peace Walker on PSN with PS3 online multiplayer. The publisher-people even wrote down answers, apparently.
Kojima Productions already has a new, fully-fledged Metal Gear Solid console game in development in the shape of Metal Gear Solid: Rising.
Metal Gear Solid: Peace Walker features four-player co-op and will be released in Europe this June.
MGS: Rising has no official date and is unlikely to be released this year, given the amount we've seen and heard so far - i.e. not a lot.
