During Nintendo's E3 2011 presser this morning, Super Mario creator Shigeru Miyamoto revealed that Nintendo DSi owners will be getting a free copy of The Legend of Zelda: Four Swords Adventures. No, we're not really sure how a GameCube game with GameBoy Advance functionality will end up on Nintendo's DSi, but we imagine it'll have the GameCube game on your top DSi screen while the GBA part of the game shows up on the bottom screen. We'll be sure to ask Nintendo for more details as soon as we can.
