Wow! Wait, so the source is...someone who knows Japanese and German working in Kyoto who was helping Eiji Aonuma prepare a speech for E3. Took a while for me to figure out... so he passed on the info by IM to someone. That someone posted on a German Zelda forum at zelda-forum.com. The info was reposted at consolewars.de, and someone emailed the rumors to Zelda Informer with a link to the forum.
Phew! Someone tell me if I'm wrong. I'm definitely getting this... unless it's a sequel to Twilight Princess. In that case I'll get TP first and then this new game. Also, since ZeldaWiki is affiliated w/ Zelda Informer, NIWA will definitely get some notice.
