The Legend of Zelda fans comes from a recent interview in Famitsu magazine, via Andriasang. There, director Eiji Aonuma says he hopes that Nintendo will be able to "show something playable" at E3. What? That's, like, four years ahead of schedule! We jest, but it's not like Nintendo really needs to rush anything. It's The Legend of Zelda. You want it, even if it's supposed to be different this time around.
Aonuma wouldn't provide much in terms of how far along the game has come, other than talking up the MotionPlus support and stating the team has "progressed in development since last year" and that the "core areas have come into clear view." We take that to mean the team has finished rendering Hyrule Field.
