Nintendo CAN'T turn their back on this game now.
It would be suicide.
The reason why I loved WW and Link was because it was so fluid and animated - facial expressions, body movement, his eyes - you just fell in love with him! And the enemies were awesome too!
If they could carry those same emotionally charged animatics into the realistic Zelda then by GOD that would be heaven. Star Fox Adventures was a great start.
Sweeping romances, as Bill (
) said, and epic battles is the next revolution in Zelda. Sure there still will be exploration, but massive real-time battles would be cool too, perhaps we will actually see the Hyrulian Army in action, rather than just being mere guards or mentioned in story, with Link as the leader!
Ok, so it won't be on the scale of Lord of the Rings, but given the epic look it has already, and the fact that Link really does look like a battle-weary soldier, that should be more a possibility now.
