Will God of War 3 Ever Release on Xbox 360? Absolutely Not.
There is zero chance. Zero. None. Never.
Why This Is Certain
First-Party Exclusive: Sony owns Santa Monica Studio and the IP. Exclusives exist to sell PlayStations.
Business Strategy: Porting a system-seller to a dead competitor (360 discontinued 2016) makes negative business sense.
Technical Barrier: Engine (Kratos Engine) heavily optimized for Cell SPUs. Port = rewrite. Cost > any possible 360 revenue in 2010, let alone now.
Precedent: No mainline Sony first-party game has ever launched on Xbox. MLB The Show went multiplatform in 2021 — but that was a licensing requirement, not a choice.
Even God of War (2018) and Ragnarök came to PC years later — but never Xbox. The 360 is two generations dead. Let it go.
