Aaah, the Pocket Lint article...I knew you were talking about that. Well, I don't really think you should assume anything said in that 'interview'.
There is a possibility that the 'interview' part of the article (I'm talking about the Miyamoto quotes in the article) is in fact old, and thrown in with the rest. I'll try to explain.
First I suggest you read the whole article (I'm sorry if I seem like a smartass, but just to be sure :p)
http://www.pocket-lint.com/news/37425/interview-shigeru-miyamoto-nintendo-zelda
Then to start off, you'll see that somewhere near the end of the article, they start talking about 3D. Not specifically the 3DS, just 3D. That's odd, but not noteworthy. But when the writer says something about Mario Kart 3DS (that it presumably looks great) Miyamoto reacts weird.
Specifically: "For the briefest of moments, Miyamoto looks like Pocket-lint has stolen a prized biscuit from his private cookie jar, since no announcement of Mario Kart in 3D has been made."
As we all know, Mario Kart 3DS was oficially announced at E3 in June. This would mean that at least this part of the interview is at least 5 months old.
If you go back and read some of the Zelda stuff, you'll also see that Miyamoto never refers to SS by it's title, just calling it 'the new Zelda game'.
Now, with this there are 2 possibilities:
1: This article is made up of at least 2 different interviews, the one with Mario Kart (which is before sometime E3), and a recent one about Zelda, with Miyamoto just not wanting to say 'Skyward Sword' all the time thus saying 'new Zelda'.
2: It's just one pre-E3 interview, so Miyamoto isn't allowed to name Skyward Sword.
To me, the second possibility seems more likely. Especially since the article seems to stress the part about SS being over half complete
at the time of the meeting.
I can't really say this is the truth, but the interview(s) used in the article seem strange enough.
