Before the rumor managed to fully set in and plunge the masses into unyielding seizures of delight, the article was promptly pulled from the site and replaced by a decidedly unhelpful update. "At the request of our sources, who do not wish to go to jail this week, we have temporarily removed the Wii rumors piece that was posted earlier." Apparently, the oppressive and joyless Nintendo police were none too pleased with people blabbering about portable Gamecubes to IGN. When the article reappeared, all mention of it had been removed, spirited away to some great rumor recycle bin (send our love to the holographic projector).
Perhaps that's all there is to this story -- there is no portable Gamecube and the article's editing serves no purpose other than to make it more accurate. Of course, when an article is admittedly based entirely on whispered secrets and industry murmurings, why yank it just to edit out one rumor in particular? Or could it be another high-larious prank devised by Matt's IGN pals? Time will tell, though we'd rather it be an impatient and stocky time attending the Leipzig Games Convention.
