you might remember back in 1999 when PS2 was  unveiled,  Polyphony had a 
GT2000  which was basicly a demo using a very souped up GT2 engine from 
PS1 - but the graphics were dozens of times more detailed than GT2 on PS1.

well, it seems that Vision GT for PS3 is the same sort of thing. it uses the 
GT4 engine from PS2 and bumps it up to HD high-res, and obiously uses alot 
more polygons.     Vision GT  is *not* GT5, just like  GT2000 demo on PS2 in 
1999 was not  GT3 A-Spec

Polyphony says they want the eventual GT5 to be 100 times more detailed than 
GT4
