I'm hoping it's because at some point of development they saw this game could end up as empty as Twilight Princess was and decided to spend the extra time to fill it.
BUT... You also have to remember that they were so slow developing Skyward Sword after 4 years they had to pull in Monolith to finish it off for them and that game was also really small. Perhaps the new Monolith Studio near Nintendo's HQ has been working on this for a while and the main team now they've finished Xenoblade X will be dropped on it to fully complete it? Nintendo's core teams seem to be spread too thinly across the ground. I'm hoping the new president will fix this long term problem which dates back to the Gamecube.
