Gran Turismo's dad Kazunori Yamauchi has told Eurogamer that Gran Turismo 5 is "at a point we can release it any time we want".
"I want to release it as fast as I can," Yamauchi told us, "but GT5 for us, when you talk about its status, it's at a point we can release it any time we want, but we can always keep working on it. It's very important for us to make sure everything is done perfectly and everything is done in detail."
Yamauchi also discussed possible connectivity between Gran Turismo PSP - due out with the PSPgo on 1st October - and GT5. "We're hoping maybe to make it so you can share the garage with the PSP version so that cars you unlock on PSP will be available immediately on GT5," he said.
Elsewhere, Yamauchi said the PSP version would hopefully be about a gigabyte in size when it's released for digital download, but it's unlikely to receive any downloadable content afterwards.
