GameStop is doing pre-orders. 
http://www.gamestop.com/Catalog/ProductDetails.aspx?product_id=76865Eiji is hoping to make a demo that can be played at E3. He is working hard to get the game out this year. He also said that the game is very far in development, and the final version is already in sight, with core areas in the clear and that they are now polishing and completing the project. 
He has also said that a lot of the theories made on the Internet were right. He was specific to what theories he was referring to.  This assumption was made right after it was asked what the girl in the artwork is. 
Could the girl be the master sword? It’s the only that successfully spread throughout the Internet. 
Eiji-
"Our team has been working on making the building blocks regarding the action - the scenarios, dungeon-making and so on. We are well underway"Chef of Game Informer, Andy McNamara got his hands on early as well as incredible info. “I know of at least six other games releasing this year that will make your blood boil in anticipation" he said in issue 201 of Game Informer. 
Could of these games could be Zelda Wii? Iwata answered this question with a yes, one of the games is Zelda Wii. 
Zelda Wii will go on sale sometime after its announced in June at E3.
The game will be more realistic with more time on the overwold and less time in dungeons.
Link will be an adult.
Wii motion plus will be used for sword control.(he maybe right handed again, If your left handed he maybe left too)
Will post more later when I find the info.
