Yes, before we even see a trailer for Wii Zelda, information already comes out from a somewhat credible source that the highly-anticipated title has already been delayed for next year to see if Wii Motion Plus catches on. As in, they don't know weather or not yet to make Wii Zelda Wii Motion Plus exclusive or not. 



About half way into the video, they mention that Miyamoto explained that the success or decline of Wii Motion Plus is why Wii Zelda was not shown this year. Personally, I would hope it's Wii Motion Plus exclusive, but since it's a new to the market they haven't gauged its success yet. Hey, at least this is a better excuse then "we're going to launch it on our next console".
