Polyphony Digital head Kazunori Yamauchi has told Eurogamer that he "doesn't know" if the next Gran Turismo game will release for PlayStation 3 or the next generation of console hardware.
"10 years ago it was easier to predict what would happen three years in the future," he said in an exclusive interview at the official GT5 launch event in Madrid. "Nowadays no-one knows what happens in the future. In three years, we don't know what will happen."
Pressed on whether the game would miss this generation he laughed and shrugged.
With GT5 finally releasing today, Yamauchi-san also responded to criticism of the online feature set, revealing to Eurogamer, "Online updates are planned of course for leaderboards and matchmaking - [they're] all planned in the process of evolution."
During a stage presentation earlier in the evening, Yamauchi pledged that his team would be "upgrading every week, every month" to improve the game, which took five years to develop.
Yamauchi described the game as a "pet" that his team had "nourished and looked after," paying special tribute to fans, "all of whom have helped and supported us to develop Gran Turismo."
Beneath a video screen slogan which read: "Today is not the finale. Today is only the beginning of a new era for Gran Turismo," the series creator insisted that his team's work on the project was far from complete.
Tonight also saw the formal unveiling of the Red Bull X1 – a prototype car designed by Red Bull engineers exclusively for the game. Hidden under a black sheet on stage, the car was revealed by Yamauchi and Jaime Alguersuari, the youngest ever F1 driver.
F1 world champion Sebastian Vettel appeared in a video message to say: "I had a good chance to get some laps in with the X1. I'm pretty sure you will all enjoy this game."
We'll bring you our full chat with Kaz later in the week.
