Doing things in high definition takes longer. We all know that. The average car in Gran Turismo 4 was made up of over 4,000 polygons. The figure for GT5 Prologue is meant to be higher than 200,000. Being pretty goes a long way, but with 71 cars and just six tracks (High Speed Ring, Daytona, Fuji Speedway, Eiger Nordwand from Gran Turismo HD Concept, Suzuka Circuit and a section of central London), it will have to go a very long way, right? That's not a lot of content, even when you factor in a second variation of each track. GT4 had 721 cars. GT5 Prologue launches in Europe with 71. We may be 11 million polygons ahead, but we're 650 cars behind.
