According to Kagari (a GameStop employee), the North American release of the Metal Gear Solid 4 Limited Edition box set will feature a soundtrack CD, along with an extra Blu-ray disc.

The disc is said to include an interview with the game's producer Hideo Kojima, two 'making of' documentary, videos, and four chapters from an MGS graphic novel.

Finally, those who pre-order will also receive a free MGS artbook at the time of purchase. In total, the LE set is set to retail for a hefty $84.99.

Bear in mind this is all still unconfirmed at the moment, however, stay tuned for further details as they are available.
