UPDATE/EDIT: Remember rogersbase said Nintendo was going to reveal something soon and his hype meter was around 8-9? I mean, that's a perfect hype meter range for a remake. Also, they did just recently add the icon to the eShop a few days ago. Pretty sure it's an HD remake at this point.

There was a menu icon of Twilight Princess that was added recently. It does say Twilight Princess HD (-Thanks to Skullwaker for noticing this), although there is no extra data on it besides the icon and that. *(Skullwaker noticed this next bit as well. The icon does not have the Wii logo on it like the icons for Super Mario Galaxy 2, Metroid Prime Trilogy and etc). So, do you think it could potentially be an HD remake since fans have been claimoring for it and they have remade the bigger Zelda games? (Ocarina, Majora's Mask, Wind Waker) I mean it would make perfect sense. But a lot of people don't believe Nintendo would do it.

Nintendo also did HD tests with Twilight Princess and Skyward Sword when they did it with Wind Waker. I could see Twilight Princess for Wii U, and then Skyward Sword for it's successor.

I'm guessing it's just a Wii port to the eShop.

An HD remake would be awesome, but I highly doubt it.

No, it'll be a Wii port.

To be fair, there is some information suggesting otherwise.

Like?

I hope they fix a lot of the issues with it and not just add lens flare and bloom all over the place. And, add extra content, too.

The data file is titled The Legend of Zelda: Twilight Princess HD.

The icon isn't simply the game and Wii logos, like all other Wii eShop games.

I think its a wii port BUT i wouldnt be shocked if we hear about this during the new direct.

If it is a Wii port, I wonder if NA will get it 3 months later than everyone else again.

Wait, so the only info the tweeter found was the picture in her tweet? Cause I don't see anything saying TP HD there.

Hmm, interesting.

Maybe the logo suggests that this is more than just a VC release.

For now, I'll just be very skeptical.
