The North Korea Sony leak showed that they have (or at least had) a deal with Sony for a CGI Super Mario movie. So perhaps they're just waiting to announce that once they have a director/writing staff attached.
That wasn't a vague leak either, it stated that Avi Arad at Sony (and the guy who also involved with Marvel) flew to Japan and celebrated with Mr. Iwata and Mr. Miyamoto to seal the deal.
So that's probably happening.
I get the sense what's happening with Zelda is Nintendo is shopping the property to different studios/outlets seeing who gives them the best pitch for it, so that's where the Netflix leak came from, but it doesn't mean they had a deal with Netflix, just that Netflix was one of the companies bidding or being approached by Nintendo to see what their approach would be.
