I am honestly not bothered by the timeline because it largely doesn't try to really retcon anything that has already been established which is my problem with the Compilation of VII which took a "go big or go home, let's copy every anime stereotype" approach to a story that was originally awkward but at least sensible. Zelda doesn't really have that problem mainly cause most of the games are set so far apart from each other that it's hard for them to really derail the mythos. A prequel will create more questions but considering this is a franchise that will exist until it stops making money, I, nor Nintendo, don't really see a problem with a story that asks more questions about the mythos.

This is coming from somone who doesn't even like Skyward Sword because of what it does to the plot but I'm willing to let Nintendo try to sell the whole "Zelda is a reincarnated Goddess" and Ganondorf/Ganon is a physical curse caused by a one-dimensional demon from the distant past. Like Del said, the story was never the series selling point it was the gameplay, the developers themselves admit this. I don't see the problem with another prequel, nor do I really see the value of moving forward at this point. Skyward Sword got me curious about Hyrule's past and lore, ignoring it seems like wasted potential.
