Blaming FE for Sakurai's apparent indifference towards LOZ again? Sigh.
I agree with the poster above, it's not Fire Emblem's fault that we haven't seen a Zelda newcomer for so long. Fire Emblem gets a new protagonist every new game, with new abilities and all. Zelda gets the same cast, but reincarnated in a new skin, with more or less the same abilities. This is a major obstacle for getting a Zelda newcomer, and a major boon to Fire Emblem.
