Polyphony Digital's Kazunori Yamauchi says that fans can expect Gran Turismo 7 "in 2015 or 2016" on the PlayStation 4.

In an interview with GamesTM, Yamauchi says that the new system should pave the way for a better game. "PS3 was much, much more difficult," he said. "The high quality of data that we have being rendered on the PS4 I think is going to make an incredible difference." 

Yamauchi didn't dive into the feature set of GT 7, but it's ambitious. "For GT 7, myself and my staff have a clear vision: to do everything we couldn't do in GT 6," he said. "We want to make it very Gran Turismo. By that I mean it's going to be a game that matches the very era that we live in, in 2015 or 2016."
