I'm not sure if I should belive this or not. The anonymous source that has links to Nintendo was also used for a cover-up for someone talking about a OoT remake for Wii.
Edit: turns out there was some trouble seeing the link in this post, so I replaced it. Here it is plain as day.
Wow very reliable. I bet his inside source is his friend's cousin who happens to know Shiggy and the gang.
Anyway, the article kind of contradicts what Shigeru was saying about not showing any footage of the game until they reach the late stages of development, so I doubt that this is true.
On the other hand, it sounds reasonable that they would show something at the next conference as Nintendo admitted that their E3 show wasn't the best and would probably like to get fans (and media) excited again.
