Someone over at IGN noticed that these two areas appear to be almost identical. Unflooded Hyrule and flooded Hyrule?
Someone else tries to disprove it:
I suppose it's logical seeing as this is the sequel to WW. As for the differences, it could be that these scenes take place at different times. More time traveling? Well, at least you'll be swimming instead of sailing...or so it would seem.
