In an interview with Famitsu, Kazunori Yamauchi said that „Gran Turismo 7“ is already in the works at Polyphony Digital, and it should be out in „a year or two“ on the upcoming PS4:
“The PlayStation 4 game which we’ll likely call GT7 will be done in about a year or two, I think, and I think the community aspect’s going to be vital there as well.”
So, the full-on sequel could be ready sooner than series fans might expect.
Yamauchi also added that while the PS4 is obviously more powerful, the extra power didn’t excite him as much as it could because the PS3 „is still really capable“…
“The PlayStation 4′s large memory size is a unique trait but in terms of CPU performance, the PS3′s Cell chip, while difficult to handle, is really capable. They both have different advantages. Besides, I think the online community aspect, one of the most fun parts of GT, doesn’t have anything to do with the platform.”
