Well, this was expected. In case you don't know, since 2000, there has been a Zelda game every year.
2000: Majora's Mask
2001: Oracle Games
2002: Four Swords
2003: Windwaker
2004: Four Swords Adventures
2005: Minish Cap
2006: Twilight Princess
2007: Phantom Hourglass
So if this IS true, then Aenuma REALLY better rush on this project, cause he only has a few months to bring it to shore shelves!
