While they are only confirmed as being sold in Japan for the moment, they have announced that the PS3 and Xbox 360 will sport more than just the game.
The PS3 game will include a 'making of' video while the Xbox 360 version will come in a metal case with a soundtrack CD, and that's before getting to the Limited Edition.
The Limited Edition for Resident Evil 5 will come packaged in a special box what'll contain the game, a 2GB memory stick, a 32-page art book and a waist pouch based off the in-game one.
Again, so far the releases of these special editions for Resi Evil 5 are confined to Japan only, let's hope Capcom plan to share the love.
