Polyphony Digital boss Kazunori Yamauchi has provided an update on the development of Gran Turismo 7 for PS4.
Speaking to Eurogamer, the Polyphony CEO reiterated that work is currently underway on the PS4 instalment, as well as confirming that the racer is unlikely to release in 2014.
Yamauchi also said Polyphony will go straight into development on the full game, rather than working on a smaller Prologue version, as it has done with previous iterations.
"We are working on the title," he said, adding: "I don't think it'll make this year," and "I don't think it'll be a Prologue."
Yamauchi also suggested the series will continue to utilise its library of less detailed, 'standard' car models, which originated in Gran Turismo 4 on PS2.
"I doubt that we'll be throwing away the standard cars," he said.
"Each car has its own fans. So I think we'll hang on to the archive. In the meanwhile, some of those cars we may be able to make into Premium cars as they become available - but basically we're more focussed on increasing the number of premium cars."
Polyphony first confirmed it was working on a PS4 GT in 2013, although series fans will know to remain patient for its release, as the series is notorious for its extended delays.
Gran Turismo 5, unveiled in 2006, suffered a series of delays that pushed the game back from its initially expected 2008 release to an eventual late 2010 release, stretching its development time to around five years.
