In an interview with Famitsu [via Andriasang], series creator Kazunori Yamauchi said the best scenario for Gran Turismo 5's future would be to have a regular update every month, including updates to existing vehicles. While Gran Turismo 5 launched with over 1,000 vehicles, only a selection of them were presented as "premium" models--which features higher resolution textures, interiors, damage modeling and more.
According to Yamauchi, there are plans in place to upgrade current "standard" model vehicles to the same quality of "premium" vehicles. "Among the standard cars are some historical classics, and we plan on remaking them as premium cars. There are currently some cars that have both standard and premium versions. Those are cases where the cars were remade." Yamauchi did not clarify if these upgrades would also come with a premium price tag.
The focus for the updates is said to be specific to new features and the game's updated models, leaving little room for downloadable vehicles and courses. "They may be added as expansion content," Yamauchi added, "or we may leave it until the next title."
Before you jump up and down on the desk squealing "Gran Turismo 6," Yamauchi explained there is no current plan in place for the franchise's next entry. "If this were ten years back, it was relatively easy to predict what things would be like in three years, but now it's pretty much impossible to predict three years into the future," he said. "Even if I were to say 'The next title will be like this,' three years later it would end up being completely different."
Sony Computer Entertainment of Japan recently revealed a plan to give away three vehicles during a limited "holiday" window. When asked whether other regions would also receive the content, an SCEA representative told Shacknews, "We don't have any news on updates for North America."
