Why/why not?

Yes yes i will

Yes.

I really feel like I didn't get a fair shake when I played TP for the first time. It was the Wii version, and the graphics certainly did not help my opinion. The improved visuals and better controls are more than enough reason for me to try this game again, although I do hope they attempt to fix some other issues of the game as they did with WWHD. Also looking forward to seeing how they implement the gamepad (if at all).

Not sure yet, mainly cause there are other games I wanna get next year, including Fire Emblem Fates, and Star Fox Zero.

Will you buy ff7 remake?

Yes I will.
I greatly enjoyed Wind Waker HD and I'm confident that I'll be able to say the same for the Twilight Princess remake as I look forward to some new changes and elements they might bring to it.
Although, unlike the Wind Waker remake, which was the very first Zelda game I ever played, I have played the original Twilight Princess before, albeit it's the Wii version I own. So having said that, playing the HD version which looks to be the original GameCube version will prove to be quite a different take and experience for me.
Also, Twilight Princess is one of my favorite Zelda games of all time.

I won't but not because I don't think it will be a good remake, I still have the GameCube version here and have played through it twice before - I didn't buy the Wii version because the game wasn't designed with motion controls in mind and I'm a left hander too!
I also didn't buy the Wind Waker Wii U remake - I prefer the GC original. For newcomers to these games I say go for it but I can't justify putting another 40-50 hours into a game I know backwards because it looks prettier.
Zelda Wii U on the other hand - I'll be lining up at midnight day 1 for that sucker.....

I'm guessing it'll be like with Wind Waker HD where it'll be used to change your items and manage your inventory on a whim. And probably whenever you want Midna to warp you to a new location, the whole map will open on the screen and you can tap on which ever warp panel you want to travel to and boom.
That's just off the top of my head.

Yes. It's the gamecube version. And I don't own the original game. That's my rule with ports/remakes. As long as the pro controller is usable.

Yes, because I have never owned it, and I'm willing to give it another shot. Last time I played it, I really didn't really enjoy it.
