On the January 29th update on the Smash Bros Dojo site, all of the music initially available before unlocks were listed. Only this time, the specific game that each piece originated was listed. Of that list, there are songs from each Metal Gear Solid game.
The twist? The primary song (first listed) is a piece from Metal Gear Solid 4. Why would that piece be included? Every single song on the list is from a game that has appeared on a Nintendo system, or will soon. Does this mean that a version of MGS4 is indeed Wii-bound? Only time will tell, but this rumor is no longer as absurd as it once seemed. Below is the information listed at www.smashbros.com
MGS4 [Theme of Love] SSBB version
Metal Gear Solid 4: Guns of the Patriots
