When is the new modern warfare game released on ps3 and What background to it?

There is no new Modern Warfare game released on PS3. The last Modern Warfare game released for PS3 was Call of Duty: Modern Warfare 3, which came out in November 2011.

Here's why there won't be any new Modern Warfare games on PS3:

* Hardware Limitations: The PS3 hardware is significantly outdated compared to current-generation consoles like PS4 and PS5. Modern Warfare games require powerful hardware to run smoothly and deliver the graphics and gameplay expected from the series.

* Focus on Newer Platforms: Developers like Activision focus on developing games for the latest platforms, where they can reach the largest audience and utilize the latest technology.

While there may be some older Call of Duty titles available for PS3, there are no plans to release any new Modern Warfare games on the platform.
