Speaking in an interview, series creator Kazunori Yamauchi explained how the game will be updated following its release. "Everything's very tight. It's an incredibly tight schedule. As to being able to include everything we want to on day one, we probably won't be able to," he said.
"I think for the 12 months following the release we'll continue to update the software. Because in Gran Turismo 6 we're preparing a lot of different things we haven't even touched on yet."
Yamauchi elaborated that the game's online features are still being worked out before the game's launch. "I can be almost certain that there'll be a day one patch applied," said Yamauchi. "The online features are already working--we'll be updating it with a day one patch, and we're still overflowing with stuff we'd like to do. So I think the day one patch will be a fairly large patch."
Discussing the future of the series, Yamauchi also reflected on whether Gran Turismo could ever become a service-based game as opposed to a series of numbered releases, and added that studio Polyphony Digital is now able to work a lot faster. "I think you're sort of right in that we've really changed how we make games now," he said.
"Even now when we're near the end of development [of GT6] we're still creating features that will be provided in this game in updates later on. I think it's a possibility that one day these types of update will be continuing for our titles. More recently, the speed of our output is much, much faster."
Last week, Polyphony said that Gran Turismo 7 for the PlayStation 4 would be released in "a year or two".
Gran Turismo will be released for the PlayStation 3 on December 6.
