Technical Debt: Porting/optimizing for 360's PowerPC/Unified Shader arch is costly for zero ROI.
Realistic Possibilities
Remaster/Remake on Modern Platforms: PS5, Xbox Series, PC, Switch. Bully: Scholarship Edition (2008) already on 360/PC/Wii. A new remaster would target current hardware.
Sequel: Rumored for years. If real, current-gen only.
Backward Compatibility:Scholarship Edition (360) plays on Xbox One/Series via BC.
Watch Rockstar's official channels. But a 2024+ Xbox 360 release? 0% chance.
