The Train has set sail.
I don't know, it looks okay, a Zelda game is a Zelda game. People thought Wind Waker was going to be !@#$% but it was one of the best Zelda games. People also thought Phantom Hourglass was going to be terrible but it turned out to be good.
The whole train think does look a bit weird, but whatever. It's cool to see Hyrule restored (or at least, what I'm guessing is the new Hyrule).
I didn't mind the controls for PH, at first I didn't really like them but I got used to them. At least it's not waggle.
Look at the screenshot
The castle in the background is HYRULE CASTLE. The Windwaker world was flooded Hyrule.
This could also take place a couple years after PH or even much longer after that. Could be a new king of Hyrule and all.
About it being the Hyrule Castle from WW, the positioning and landscape around it really looks like nothing the one in WW. There were no cliffs or anything beside it like that IIRC.
