Yes. Twilight Princess is my favorite Zelda (game?) of all time. If Nintendo is offering a newer, better, definitive way to play that game, there's not even any hesitation for me. In fact, I preordered the TP:HD Amiibo bundle the second it came up on Amazon.

I can virtually guarantee that you will be able to play TP:HD with a Pro Controller. WW:HD had Pro Controller support, so it stands to reason that TP:HD will as well. 

I will be buying it probably cause I never really played it on Wii or GC and the Wii version's waggle controls turn me off to hat version. This one looks better, has traditional controls, and will probably at least have WWHD's gamepad features. So yes, will buy.

Better hurry selling it before the game comes out.

I will definitely get Twilight Princess HD. The graphics look better (plus there is time for a little extra polish), and I am interested in how they are going to implement the Zelda Amiibo line into the game, as well as the new content that they have not covered yet.

I am hoping that they will add in some new side quests; they added in a new side quest(s) for Majora's Mask, and that game wasn't exactly short on side quests either (plus two new areas).
Every temple in Twilight Princess had two chests that contained a heart piece. They could easily remove at least one heart piece from each respective dungeon and add in some sort of quest and/or mini-game to earn the heart container.

Not unless they add any extra dungeons.

Going to get it day one. Love TP, finished the Wii version several times. Last year I tried the Gamecube version, and it was very difficult to navigate due to the mirrored world, and it seems this version will have the original GC map (or both!). That's something I'm looking forward too.

No.

Reason: Lazy port.

This is an interesting point. For those who played the Wii version of the game, it seems as though TP:HD will be like experiencing the world for the first time again. Not exactly, of course, but the fact that the world is mirrored means it will all be different. It's one thing I'm really looking forward to actually. 

Man, there is so much hate for the Wii version of Twilight Princess in this thread. I'm not sure if it's due to this almost hipster mentality that the lesser played GameCube version is superior, or the loathing of motion controls that seems to run rampant these days. I don't get it, I loved Twilight Princess on Wii.
