RPCS3 - Roadmap
[url=https://rpcs3.net/roadmap#short-term-goals][/url]

• Improve SPU/PPU LLVM recompiler compatibility, add more optimizations. (Nekotekina)
  
• Implement parametrized PPU/SPU Interpreters reusing current LLVM IR generator, remove original hard-coded interpreters and make LLVM mandatory. Add options regulating its accuracy detached from the base choice of the Interpreter or the Recompiler. (Nekotekina)
  
• Make journaling VFS layer or something that fits, properly implementing some missing features like case sensitivity. (Nekotekina)
  
• Fix any remaining RSX regressions. (kd-11)
  
• Fix surface cache leaks. (kd-11)
  
• Merge RCB+RDB and WCB+WDB and make the new 'Read Buffers' option enabled by default. (kd-11)
  
• Rework RSX <-> Cell synchronization framework to be more cohesive. (kd-11)
  

Are these "short-term" targets that are really pursued internally? I ask because the main developer mentioned there "Nekotekina" is no longer on the project, and even when he was it doesn't seem like things were happening. Just curious to know.

The roadmap hasn't been updated in a while, we'll get to it at some point, you can follow the open issues assigned to developers in the meantime for upcoming work
