Looking back at what Tantalus said back in Feb this game was suppose to come out this year.
From Tom Crago (Tantalus)
"Were doing that. It hasnt been announced, but it will be soon. And can I just further add to the mystique and say that its big. Its the biggest thing weve ever done. And itll come out this year, and I hope it wont disappoint."

Now that I think about it, the reason they were so quite on it was the fact that it was a Nintendo 1st party game and Nintendo doesnt like you to blab lol.
I think it was mostly delayed for the 30th anniversary and also prob needed more time. So i'm guessing it was gonna be a Summer and while Zelda U was gonna be Fall, but Nintendo pushed both to next year to give them more time and to come out for the 30th anniversary.
This is def not a rushed port like some people were claiming
