I was wondering, are the graphics of the final product going to be upgraded from Prologue or will it be very similar? I know polishing will be done but did they say anything about drastically changing the graphics? I'm wondering this becauase in E3, everyone was pissed that we didn't get to see any gameplay of GT5, but can't we expect it to look just like Prologue?

It will be WAY better.

I imagine the graphics would be improved for GT5.

I mean, GT5P looks good, but i expect better out of GT5.

Expect an improvement. Not a vast one but a considerable one. The biggest changes will be in sound FX and physics though (hopefully).

It should be better. It'll be about 2 years or so later than GT5:P so improvements are inevitable.
If it releases soon of course.
The graphics will be even better if they only release it in another two years from now, and can you just imagine how amazing they'll look if they never release it?

It's using the same engine, so it won't look drastically different.

July 9, 2009 - It's been a long time coming, but E3 2009 provided us with our first real look at Gran Turismo 5 in the form of a trailer. While GT5: Prologue gave us little hints at what we can expect from the final game, it's become clear after seeing the trailer that Prologue didn't even scratch the surface of what we can expect from GT5's release.

While the trailer is certainly fantastic (click the link below to watch it if you haven't already, or again for a refresher), running through it with a fine-toothed comb presents us with a couple new clues as to what we'll see in the game. Since Polyphony is being absolutely silent on the game right now we can't get official word on anything, but that doesn't mean that we can't pretend to be Sherlock Holmes and dig up our own details.

Is it Real?
Upon first glance the trailer might almost look too good to be real. I met with Kazunori Yamauchi at E3 to play the PSP version of Gran Turismo and the first thing that I asked him was if the GT5 trailer was real or not. He looked a little confused by the question and basically responded with, "of course it's real".

Slowing down the trailer proves this to be true as you can see some rendering issues and things that wouldn't happen if the trailer was pre-rendered. Here are a couple things that I noticed.

In this section here the cars race down a straightaway lined with trees. If you look at this section in the video you'll notice that while the trees have cast shadows on the ground, they aren't picked up on the cars. While the shadows could have been baked into the scene (read: computed ahead of time and essentially rendered as a texture), if this trailer was going to be pre-rendered then this doesn't seem like a shortcut they would take.

This image is a very pretty shot of a rally car racing through a field, but take a close look at the hay barrels out in the field. Their shadows are rendered through their model, appearing on top of the hay. Any professional rendering software would never cause this error unless a shader was created to ignore the z-buffer or something. So, it's a rendering issue with the build of the engine used for this video (that will undoubtedly be fixed before release).

One last piece of evidence that further proves the trailer is all in-engine is that the flags that you see at the beginning of the video clip through the poles holding them. While this could happen if you didn't set the cloth physics sampling rate high enough in a high-end 3D package, it's unlikely that anyone creating this scene that way would have let this happen. Despite this subtle clipping issue, the cloth physics here are pretty astounding for a current game engine, especially a racing title that doesn't really need anything like this.

Of course, I had to search pretty hard for examples like this as the game looks absolutely incredible, and even these tiny issues may be fixed by the time the game ships, making it all the more closer to being flawless.

it'll be so much better that your TV will melt, all this because of the CELL and it's awesome power!!(limited by ram of course... which is already almost used to it's max, so errrr....)

Thanks for the read good sir

It won't look much better. GT5P is already beautiful.
