All I know for certain is that there's possibility with this. Almost every Nintendo machine I've bought I've done so because I wanted to play the Zelda title for it. This is the first announced game that's made me consider getting a Wii U to any extent. BUT, I'll need more information to determine several key factors.
1. Will there be the option to play Link as a lefty? Call me a purist, but I've always kind of liked that he was a left handed hero pre-Wii. And mind you, I'm right handed.
2. Will it still FEEL like a Zelda game? I like open-world, but I play Zelda games specifically for the action-adventure puzzles. Don't get too much of your peanut butter in my chocolate.
3. Is it going to have the Link Between Worlds thing of doing dungeons in whatever order? I find that decision to be an odd and contrary one. After all, as you progress, the puzzles are supposed to get a bit more complex as they require using the items you've found in the previous dungeons, giving you greater satisfaction for figuring it all out. I've not played LBW, but knowing that that was a decision Nintendo made has made me even less interested.
4. Are they going to program a bunch of ridiculous stuff in related to the attempts at integrating social networking? If so, that'll DRASTICALLY reduce my interest.
5. Will I be able to play this game with my Gamecube controller via adapter?
Most of these questions will probably be answered when Yahtzee reviews this game. And I'm pretty sure he will, as the open-world thing alone means he can't just brush off all Zelda games as being the same. Until then, I can wait.
