Nintendo and release dates

[2Quick]

Nintendo delays another game?  How many times do I need to see this as a headline?  Nintendo has been inconsistent with release dates more than ever this generation.  It seems that nearly every games nintendo has is about to be realised, but never comes out.  American Wii U fans have seen significant delays for:

 

Pikmin 3

Xenoblade Chronicles X

Wolly World

Super Mario Maker

Zelda Wii U  

And now Star Fox Zero

 

I know that my european friends had to deal with Treasure Tracker delays as well.

So I ask you today, VGChartz,  Why has Nintendo become so bad with maintianing/hammering down release dates?

Is it because "they are still getting used to designing HD games?"  Is it because they announced all these games too early through the nintendo direct system?  or something else?

Are you mad about the delays?  or just dissapointed?  or do you appreciate that nintendo is raising its standard of quality?

 

Also fell free to tell me more famous nintendo delays of wii u era so I can add them above.
