I think a further factor would be the mood of the creators. Many Zeldas are made independently and then stuck into the timeline where they best fit; but Skyward Sword was developed as a prequel in every facet. That restricts the game to building toward a known ending. I would imagine the Zelda team is itching for some unrestricted creativity. That would make them want to work with the end of a timeline.
