Will Need for Speed: Most Wanted Be Remade for PS3? Highly Unlikely

Highly unlikely.

Reasons

• PS3 is obsolete: Released 2006; hardware far behind PS4/PS5. Remake ROI would be poor
• Remakes target current-gen: EA invests in PS4/PS5/PC (e.g., Need for Speed Unbound)
• Focus on new titles: Resources go to new entries, not last-gen remasters

But the Original Is Still Playable

• Original Most Wanted (2005) on PC, PS2, Xbox 360
• PC emulation (via RPCS3 for PS3 version? No—PS3 version doesn't exist; emulate PS2/PC versions)
• Need for Speed: Most Wanted (2012) – Criterion's reboot on PS3/PC/360/Vita, not a remake but a reimagining

A PS3 remake won't happen, but you have several ways to experience the classic.
