GT5 is still 90% finished, says Yamauchi

If we are very otimistic, they could complete that 10% still missing in another 6 months, so in November, but I wouldn't bet on any date.
I suspect that besides adding 3D and new car models, they beefed up physics refresh rate, if it was slower, to prevent it from falling behind FM3's one.
