Nintendo keeps everything close to their damn chest. Yoshi's Wooly World they refused to show anything new on it for like 2 years as if it was a matter of life and death security or something.

I think thats because it underwent alot of changes. Not really because they wanted to hide it.

But they are hiding bascily from moment they announced it year ago and they didn't said anything yet about. They definatly want to hide it.
