In some Zelda titles Ganondorf did take a back seat in the game. In 2000-01 Majora's Mask was released with Ganon no where to be found. Would the Zelda title be good without Ganon; maybe, maybe not. If he were in the game it would be nice if we saw more of a back story on Ganndorf instead of a five minute cut scene. Throughout Ocarina of Time we the player get bits and pieces of his background. Maybe the new title will give us more information about Ganondorf, how the goddesses picked Zelda, Link, Ganondorf, and what makes Link worthy to hold the Master Sword. Also, judging from that released picture maybe we will find out who or what the Master Sword really is. If Nintendo can get that into one game and connect it, the new title would be amazing but hey anything is possible.
