Today Konami Japan confirmed the news.
The company's Japanese public relations representative Scott Dolph told Bloomberg this morning that while a Metal Gear Solid game is scheduled for GameCube, no release date has been set. No further details were offered.
Konami's Metal Gear Solid franchise is action-based and follows hero Solid Snake as he uses his wide arsenal of moves and weapons to take down foes. With impressive graphics and play mechanics, the firm's latest in the series, Metal Gear Solid 2, was a top-seller for PlayStation 2.
Whether or not the still-mysterious GameCube MGS title will in fact be a port of the already-released PS2 game is still unknown. The title will, regardless, mark Solid Snake's debut on Nintendo's system.
Konami USA's website, in official message board postings, has recently hinted that the publisher would show off some of its bigger franchises for GameCube at the Electronics Entertainment Expo in Los Angeles this May. It's highly possible with that in mind that Metal Gear Solid for GameCube will debut at the event.
