Japanese developer HAL Laboratory has made plans to wrap up a secret Gamecube game by the end of this fiscal year (March 2003).

According to Nintendo's Satoru Iwata and Shigeru Miyamoto the game is still very undecided in terms of direction so it really could be anything. Maybe it's linked to HALs two GBA games titled Battle Land and Lunar Blaze? Or the rumored Zelda or Mario game from them?

We'll probably hear something at E3.
