Why do Zelda Console games take 5 years to develop.... ?

For example, if Nintendo took Twilight Princess, improved the graphics engine and made a plot and setting that had Gannon controlling the world and everything covered in a never-ending winter that Link needs to thaw to restore a vibrant, green Hyrule, they could have a unique experience that was true to the classic Zelda experience, but also offered a unique feeling and stetting.

Skyward Sword originally was that. They were using a similar artstyle and the Wii Remote. But someone believe it was a good idea to delay the game, implement the Wii Motion Plus and change artstyle. With a better management we could have get the original game in 2009 and a new one with the Wii Motion Plus in 2011-2012.
