Nintendo probably didn't a need to edit those things....
Epona looked good enough as it was...No need to edit her in anyway other than to make her a young horse.
Link's Tunic has hardly ever changed, It was always green, They usually just changed the design of his belt and few minor things on the Tunic itself which isn't really noticable.
The Ocarina of Time never changed because there was no need to and this would have confused many fans.
The shield changed because it was a metal one that was small enough for Link to wield normally, Not just on his back. They probably wanted a design change so they made a Metal one instead of a Wooden one.
They probably just thought "Ya know, Lets give the Kokiri Sword a make over while we are designing his shield"....
