I used to despise Zelda with a PASSION. Zelda 2 being the least. I would get nauseous from hearing or watching anything Zelda. Then I played OoT because my wife LOVES Zelda. It was the first console game we bought together :P Since then I play Zelda regularly. However I f'ing hate the Zelda dungeon formula. It's been done to death.
I want my dungeons integrated into the world. I wan't dungeons to be real locales rather than isolated pockets of underground. Real underground dungeons which exist tend to be small due to construction purposes. WW and some TP dungeons weren't so bad for that. I want the dungeons hidden as over-world challenges. Scaling a mountain could be a dungeon.
I would also love to see and end to Zelda's, rinse and repeat bosses. I want something closer to Shadows of the Collosus and Monster hunter(though not as difficult). Where bosses are truly feel epic. As it is bosses feel more like an action repeat puzzle. Though some bosses were great. I liked the Dragon fight in TP. Though the Dragon Skull was lame.
All in all I would like a change in the Zelda formula. HuB world with zones pockets to the side are sorta boring now. WW had a much better design. Open world where the locations are inside rather than corner extensions.
Anyways I can see this E3 having a showing of Zelda Wii. I know it's classic every year for people hyped to hear about the next Zelda. With year after year with very little information. This year however feels like we will get more info. Though I won't be surprised if next years E3 is when they demo the game.
