Yeah, no co-op. We don't need it in every game series, and I prefer Zelda as a single player experience. Look at Dead Space. Co-op didn't really do anything amazing, and it basically detract from the experience and atmosphere.
Zelda is about yourself going on an epic journey of discovery and saving the land, and I think those accomplishments would be diminished if you were constantly having them with someone else.
Are you guys every playing multiplayer games and exclaim "God, this would be so much more fun if you weren't here!" It can be nice to be around other people and share experiences, especially with the hobby you love.
