UPDATE: Nope, it’s not it’s an PS3 exclusive according to Konami it’s an error on the Gamestop website.
According to Gamestop’s website that seems to be the case as you can pre order the collection for Xbox 360. Konami has said for weeks that this is a Playstation 3 exclusive so I’m wondering if this was posted in error. Hopefully this isn’t the case and Konami has had decided to release the collection on both systems. I will make some inquiries to find out!
