Sony maintains its console exclusivity stance despite having developed Gran Turismo 7 for Nintendo Switch 2 internally. Industry insider Jeff Grubb revealed this unpublished version exists, continuing a pattern of non-commercial builds that include Windows/Linux versions and VR-supported GT6. These internal projects showcase Sony's technical capabilities without compromising their exclusive strategy.

These unreleased builds likely serve as testing platforms for Sony's hardware development teams. The company reportedly uses these versions to determine minimum specs, optimization techniques, and graphical fidelity options for smaller screens. The timing aligns with Sony's alleged portable gaming console project, expected to launch between 2027 and 2029 alongside the PS6.

Sony's approach demonstrates how game companies develop multiple versions of titles for internal evaluation rather than public release. The Switch 2 GT7 build exists as a technical exercise, not a commercial product. This strategy allows Sony to prepare for future hardware without diluting their exclusive library, keeping key franchises like Gran Turismo on PlayStation platforms.
