A new PS4 emulator is in development from the creator of RPCS3, though it's likely years away from running games (www.pcgamer.com)

Well, on the plus side, the PS4 doesn't use the Cell processor, so an emulator doesn't have to waste most of the CPU resources modelling the behaviour of that thing. On the minus side, the PS4 onwards (and equivalent Xboxes) have very fast shared memory; it's really cheap for the CPU to read the GPU framebuffer on consoles for post-processing effects, whereas that's a massive hold-up on PCs. And just about every game does that kind of post-processing, whether it's for colour adjustment / tone shading / anti-aliasing. Might just be one of the things that falls to brute force over the years, but it'll probably be far too slow without a clever solution in the mean time.
