Why couldn't they have done that (if they did indeed do it) to the Skylines and other cars which are pretty much all the same just minor variations, there would be alot more premiums if they did do that.
They do what they can with the modeling, if they are similar, they just take the other model and edit off of it, or vice versa, the R34 example, those we're probably the easiest ones to do, because of slight variation, they wouldn't have much to do on those but add an Apex-i exhaust on this one with a different sound file, and lower the suspension etc. Believe me when I say the skyline list was one of the easier in their department, and since there are so many of them and they have a high appreciation for them, yeah, there's a lot of em in the game lol
GT6 will be on PS3 and will come out 2012, 2013 christmas latest. Why? Two reasons. One, PD said they have started working on GT6; they are either lying or they have started working on the PS3 platform. Two, GT6 will be an expansion on GT5. More content, some polish on visuals and sound.
GT5 95% percent will sell very well, around the 10 million mark. In the 5% case it does not, is the only reason we won't see another GT on PS3.
GT5 has already taxed the PS3 to it's limits, kaz already stated frame rate dropping on the PS3, there is no way to "work on the PS3" you can do firmware updates, but you can't fix the 256mb of Vram the RSX has, Sure it's fast, but speed can only do so much. I'll explain a little about PS3's hardware without getting too techy, I've been doing computer science for 19 years, started Qbasic when I was 9 years old. And I have been doing hardware for a long time, I'm not boasting, there are others that know more than me (this is something you come to learn in the computer science field, and in all fields, some know more than you, and you share knowledge). Anyways so on to the PS3, The PS3's Cell CPU is actually great, it has 8 SPE's, 1 reserved for the console to run the XMB and other small tasking things on, and the rest of them are used by the developers for the games, the cell CPU can feed the RSX graphics card it's frame rate it needs, but when the card itself can't handle it anymore that's when it becomes a different story, kaz has already said that the PS3 has been hit to it's limit with GT5. There is no pushing the PS3 any further, this game took 5 1/2 years to make, we wont be seeing a new "gran turismo" in 1-2 years. this isn't EA, this is PD and Kaz, gran turismo games were never released in a year or 2, That's why we get such amazing games from them.
We saw 2 gran turismo's on PS2. the dates were 4 years from each other
Gran Turismo 3 - A Spec July 10, 2001 in North America on the Playstation 2
Gran Turismo 4 February 22, 2005 in North America on the PlayStation 2
that was a 4 year difference, and only 1 year before the PS3 came out.
Anyways back on topic of hardware, the way how Video Rendering devices work are, when you have a device that is giving data to a TV, a lot of things are at hand, resolution, color, dpi, contrast. the higher these figures, the harder it's going to tax the hardware. We have had a HUGE jump in what LCD/LED TV's can do since the PS3 came out, 3d wasn't around, LED TV's weren't around, TV's in 1080p (Companies started offering 1080p in 2005), and pure 1080p games JUST started coming out on the PS3. When the PS3 first came out 1080p was just a new thing, now all these TV's are getting MUCH better quality, and the games are starting to use even greater quality, put the 2 together and you get a very taxed machine. That's why GT5 will have dropped frame rates in the rain with 16 players, He mentioned that, he said it won't be all the time but it will. It's still the fact it's happening, that's the result of the limit of the PS3 and the devices it's meant to be used on. I personally don't see a GT6 on the PS3, when they can take the premium models they already have, save the data on those, build the standards up (and add in what they want or take out what they don't want) and build them up to GT6 standards and then they'll have minimal work to do on the premiums that are already there and see what the new engine in the PS4 is capable of doing. If you don't think PS4 is in development, well there's a 90% chance it is, we don't know about it. Consoles take as long as GT5 does to make, they aren't something spiced up in a year, Just the Cell CPU was a 4 year, 400 million dollar project for the PS3. So they'll take just as long developing a new one for the PS4. 4-5 years from now (like i said) It just adds up to me is all.
I see this in my head
4-5 years to develop a new console
PS3 hit it's max with GT5
4-5 years to make another PD game
all ends up adding up to PS4.
That's just me.

from a marketing perspective, they are having to limit the PS3's 3d capabilities to 720p, this is the 1080p LED/3DTV era. You can't miss it, all movies are in 3D now, they are making a 3DS. You'll see what I mean eventually.
they put in 3d in GT5, if it's so taxing on the system, and 3d being a new feature they want to implement on the GT series, why would they bring GT6 out on a system that's currently unable to handle what they'd want for GT6?
"Sony's Simon Benson explained during a 3D demo at the Develop Conference this week that their guidelines prohibit 3D games from being portrayed in the highest resolution, as it wouldn't allow for a smooth 60-frames-per-second. This means that even games that run natively in 1080p (like Super Stardust HD) will still be locked in at 720p in 3D".
"This limitation isn't very surprising, as the nature of producing a 3D image requires rendering two different images of the game at the same time. And in fact, the PS3 isn't the only 3D games platform that has to make some visual sacrifices to achieve the effect"
