then wind maker is a cash grab too..

You'll have to provide links to support most of what you claimed about the game's graphics.
Especially so, since you're misinformed about a few of them. Like the game's music. It's the same as before: It uses samples. They've only been remastered.

But here are some of the points about The Last of Us:

1: The game is still in high demand, despite being barely over one year old. :D

2: The game is going from 720p with barely any AA, to native 1080p with proper AA.

3: The framerate has been improved from 30fps to a rock solid 60fps, despite the doubling of the resolution and the original not being from 2 console generations ago.

4: In-game character models now match their pre-rendered cut-scenes counterparts.

5: Higher resolution textures.

6: A commentary track has been recorded with the game's director and the two main voice actors, which you can choose to listen as you play the game. 

7: Music was left untouched as it was already pretty much flawless and recorded using proper real instruments. ^_-

8: New console exclusive features were added to the game like game session video recording, sharing said video recording with friends, streaming it entirely, or posting it to a video hosting website like youtube. It is yet unknown if any controller specific improvements have been made. So let's not jump to conclusions about them. You can also voice chat with a friend even if they're not playing The Last of Us. =)

9: Every DLCs released for the game so far have been included on this single disc. So much for being such a despicable cash grab, right?

10: Several other gameplay improvements were implemented.

11: Improved shadows and lighting.

So better graphics and that's it, gottcha. Oh, and a commentary track.

Oh, you're a fan of selective reading. Gotcha.

Did I not delve deep enough into the several other gameplay improvements were implemented. Lol. 

what was so cheap about Wind Waker HD?

Re-recording all music with a full orchestra

Changing the aspect ratio for the game from 4:3 to 16:9 (and not by just stretching the picture or adding black bars)

Updating all the graphics

adding content into the game such as Miiverse functionality (for posting pictures, sending pictures in game in bottles for people to find and leave hints), adding a HUD on the second screen for quick map and item access

Adding off tv play

 Now what is TLOU going to do for their remake

Update graphics

Yeah, the parallels are uncanny.
