Hmmm.

Well, in the old games they simply flipped the sprite for right and left IIRC. The story used to be that he always made sure his sword was on the side of Death Mountain.

The ideal choice would have been to make Link customizable, so lefties could swing lefty and righties right (I think that's obvious but the article makes it sound like Nintendo had not figured that out). I'll be playing with my GC controller though so I suppose I would rather him stay the lefty he has been for the last three games. Eh.
