I beg to differ... they are pretty much exactly bullshots...
I mean if they aren't what is a bullshot? The models are too high poly to be PSP models (the wheels are obviously and while some body parts aren't as high poly as GT5 is likely to be, the curves are way to smooth to be PSP models), the rednering engine is not what the PSP will render, the effects are not what the PSP will do in terms of effects... at the very least it is WAY more stuff that is NOT from a PSP than stuff that IS from a PSP.
I mean we all agree that pre rendered FMV is a bullshot right? Well what is that? It's a higher quality rendernig engine, with more and higher quality effects, rendering a different and higher quality model than what is actually in the game.
Ummm... that's exactly what's going on here... I mean to get LESS GTPSP you would have to render a tricycle in a kiddie pool or something as really the only tie to GTPSP in these shots is the content (ie the type of car and the type of surroundings).
Again look at my pictures of the girls above, one is the same as the other right? They aren't bullshots... the prettier one is just the ugly one but with new flesh, new skin, new eyes, new hair, new figure, new teeth, new musculature in better looking clothes with better lighting in a nicer environement... it's the same thing, not a bullshot...
Come on...
I mean yes you could go FURTHER and make an even LESS honest bullshot raytracing some super high polygon model on an ILM super computer rendering farm or something, but as far as being a bullshot, these are absolutely bullshots.
Now as for why they didn't make a higher quality bullshot if they were going to bullshot anyway, who knows? Maybe they didn't use actual GT5 shots because they don't want uneducated people comparing GT5 screenshots with alleged GTPSP screenshots and saying "that's all GT5 can do? Not impressed!" Maybe they just don't want anyone to see how stunning GT5 really is until right up at release date, maybe they want the impact to be huge (I mean if you saw the same quality pictures 6 months earlier, it would steal some of the thunder of the release pictures - in short they don't want to take the wind out of their own sails) maybe they just hammered out a quick render on some existing engine and went with it as a quick and dirty... who knows... it's like saying "If Barry Bonds was going to take steroids, why woulnd't he take all the steroids out there in stead of just one kind?" Who knows, doesn't change what is though...
