Overview
- Jeff Grubb said on the Games Mess Decides podcast that PlayStation had Gran Turismo 7 running on Nintendo Switch 2 development hardware.
- Grubb emphasized the prototype was an internal technical test and stated he does not expect a Switch 2 release for the game.
- Neither Sony, Polyphony Digital, nor Nintendo has confirmed the test, and there is no indication of a Gran Turismo 7 launch on non‑PlayStation platforms.
- The hosts framed GT7 as a logical benchmark because it scales across PS4 and PS5, suggesting the exercise gauged how similar hardware would handle Polyphony’s engine.
- Coverage noted precedent for exclusives running on rival systems for testing, citing a PlayStation 3 build of Gears of War 3 that later surfaced online.
