TP HD looks notable better than TP Wii, some people are acting like it looks completely same.

TP HD does looks notable better than TP Wii, but I want to know what other aspects of game they improved, gameplay.

There's a reasonable improvement there. It's not earth shattering but it's probably in the order of what I expected.

Will be curious to see if it's 1080p, it should be for this kind of game. Even without reworking of assets that should provide a good bump in image quality on modern TVs.

That's a marked difference, particularly with the textures 

Seeing the Direct on a phone definitely didn't do it justice. It's not a huge overhaul or anything, but I really remembered the Wii version looking a lot better than it did.

It's definitaley an improvement. Nothing mindblowing but good enough for me to buy it. Mainly interested in other ways they might have tweaked the game a little though.

Yeah it looks good. People seriously need to chill.
