I do own WWHD, have not finished yet because XCX and a lack of time.Yeah, there did seem to be a lot of bloom, but I think it didn't really negatively affect it too much. The graphical updates were merely a nice touch, as far as I'm concerned. The gameplay fixes were what really make the HD version the version of the game. The Quick Sail and the reduced Triforce Quest were just incredible. Plus, being able to run around in first-person view with boomerang/bow/grappling hook was a really nice addition. One small thing that maybe a lot of people didn't notice is that when you conducted a song, it didn't remind you which song you just conducted every time. It told you what song you conducted once, and the next time you conducted, it just skipped that secondary little screen. Not a huge change, but one that I really enjoyed.
So ... do you think you'll get TPHD? Or are you waiting to see what kinds of changes they make?
I have pre-ordered TPHD. The Amiibo looks amazing, and we shall if TPHD is indeed better on release day.
