I don't think it means much for the whole series tbh. I'm in the camp that thinks Rauru's hyrule is still ages after any of the previous 3 timelines, so I don't have much to speculate about tbh.

I do wish we got a more linear story in the actual game though. The whole memories thing that was carried over from botw made it really hard for me to care about anything. Like wow I sure can sympathize with ganondorf when everything he did was forever ago. /s
