On June 2, 2021, a blog post was released which hinted that the game may also arrive on PlayStation 4. It was confirmed by PlayStation CEO Jim Ryan that GT7 would be delayed to 2022, citing development issues relating to the COVID-19 pandemic. On June 11, 2020, on the day of PlayStation 5 launch stream, an announcement trailer was released showing off GT7, showing us that GT7 will return to its roots rather than follow GT Sport's approach, This has been the only mention of GT7 Since an interview with Kazunori Yamauchi in 2013.

This may suggest that GT7 did indeed start development on PlayStation 4 (there are rumors that developers began receiving then-upcoming PlayStation 5 developer kits as early as March 2017, but the developer kits were not reported to the public press until late 2019). In a 2018 interview with Japanese game news site Game Watch, Kazunori Yamauchi stated that since the release of Gran Turismo Sport, Polyphony Digital have begun working on the next Gran Turismo game. (Coincidentally, GT Sport is internally codenamed as "GT7SP").

Due to the timing, it is very likely the live event pods were actually using a pre-release version of GT Sport. In 2016, a mention of GT7 was spotted in Nissan Motor Philippines' website for the 2016 GT Academy Philippines competition held between July 1 to August 31, 2016.
The target release year was not met, however.

He also spoke about how much more powerful the game will be on the PS4 and how much easier it is to develop on the new console versus the previous release, Gran Turismo 6, on the PlayStation 3. In an interview with GamesTM magazine in October of the same year, Yamauchi semi-confirmed a release for Gran Turismo 7" sometime in 2015 or 2016". He also mentioned that it will be based on the same physics engine that Gran Turismo 6 uses. In an interview with Japanese magazine Famitsu (and translated by ) in September 2013, series creator Kazunori Yamauchi mentioned that GT7 would be coming to the PlayStation 4 console "in a year or two".
